Captain Scarlet and the Mysterons

The threat that Spectrum have been awaiting for had to come, and Cloudbase being the principal headquarters of the organisation makes it an obvious target which would make seizing control over Earth a lot more easier for the Mysterons in order for them to complete their raging war of nerves, so the ""aircraft-carrier in the sky"" is targeted for destruction. With Symphony Angel stranded in the desert due to an unknown explosion on her Angel Interceptor, forcing her to eject, Captain Blue especially becomes agitated, for obvious romantic reasons, at the fact that she could die. With instructions for any aircraft entering a 100-mile radius of the airbase to be destroyed, and itself sealed from all external contact, the Mysterons themselves decide to visit Earth to obliterate Cloudbase personally, making this threat the most vengeful of all their past avengements.

The Australian Spectrum Hovercraft Centre, Koala Base, the university-style academy where several trainees are sent to brush up their skills and sit their practical and mental exams to become Spectrum hovercraft pilots, is the most likely place for Captains Scarlet and Blue to investigate, where several explosive sabotages have been made upon Koala's state-of-the-art hovercrafts, hence why the Mysterons latest threat states that there is a traitor within the world-security organisation, and that it threatens to tear it apart from within. Already settling on a few probable suspects, including the cadet leader, their suspicions rise even further when their room is set ablaze when sleeping. But when attending a routine test-run the next day, with one of their selected suspects, the duo discover that there isn't any traitors within Spectrum at all.

Professor Gabriel Carney, an awarded scientist for designing original electronics, is assassinated at his own gadgets-fulfilled home by Captain Black, in order for the Mysterons to use his skills and knowledge of the hi-tech subject to kill the three joint presidents of the Congress of Europe, additionally recognised as The Triumvirate of Europe. The names of those three men are: Conrad Olafson, John L. Henderson and Joseph Meccini, and this specific trio of men are apparently dubbed the most powerful figures on Earth, after the World President. The Mysterons elect Conrad Olafson as the first to be killed, whom is located in an underground suite, 40-feet underground Vandon Base, a maximum-security centre where plentiful Spectrum security personnel are scattered over, and in addition, the Angels commencing repeated aerial patrols over the area and Captain Ochre acting as the officer in charge of security. Their attention is diverted instantly by a realistically audible incoming military

A newly produced core reactor is being transported to the Manicougan Power Complex, which is near enough found near the Atlantic Seaboard of North America, which the Mysterons have announced that they will submit a ""heavy blow to the prestige of the world."" While conducting security checks within the designated area, it becomes aware that a missing, off-route Transporter 43, which has already inadvertently crashed over the edge of a demolished bridge, thanks to Captain Black's deliberate diversion of the planned route, is what the Mysterons are using to smuggle the reactor. With the core reactor already being aerially ferried in a shipping helicopter, and with the controller at the Expo 2068 construction site looking down at the barrel of Captain Black's hand-gun, Spectrum are back to square one before they can investigate the reactor situation. It becomes apparent however, that the copter's target is the Expo 2068 site, and evidence confirms that the thermal safety valve has been remo

Once again, the Mysterons target the Spectrum Angels in their latest act of retaliation, but it isn't actually one of the Angels, it's one of their home cities. Receiving a report from a biological research station on the outskirts of Manchester, England, regarding the theft of the phial of the K-14 virus. This is a revolutionary, & brand new strain, that has the capability to kill 10 million people. Captain Scarlet and Captain Blue start a timed race to find the station's research assistant suspsected of the theft, who is the only person to be granted access to it, Judy Chapman. Assessing that the forces' target is the Boulder Dam of Los Angeles, which the city's name stands for ""The Angels"", Scarlet places his non-indestructible life, in this particular case, on the line, to recover the phial, although he to faces imminent death.

The Chief Test-Pilot of Slaton Air Base is killed and reconstructed in a staged car crash by Captain Black, but when two medical doctors pass by, they recover the test-pilots' original body, named Major Gravener, from the lake where the car ditched in, and successfully resuscitate him in a recovery constitute. Following this miracle, the Mysteron Major Gravener attempts to leave Slaton Air Base in a fighter jet, armed with a live nuclear warhead, but is stopped in-time when the base office is contacted by the hospital who revived the real Gravener. With Spectrum investigating the Mysterons' latest threat concerning the annihilation of the world capital, Futura City, they are alerted about the bewildering incident and use the real Gravener in a risky operation, as bait, to discover if the Mysteron's will fall for the Major Gravener, and spring a net on the wanted Captain Black, even when the Mysteron doppelganger is already dead.

Concluding from where Crater 101 left of, Spectrum take a chance by commencing a maximum security operation to bodyguard radio communications expert, Doctor Kurnitz, from the Nash Institute of Technologies, up to Cloudbase to send a broadcasted voice message by Colonel White to the Mysterons base on Mars, in an effort to solve their differences, and to end the raging war of nerves between them. But the Mysteron pulsator stolen by Captain Scarlet during the expedition at Crater 101 is used as an explosive charge, to start a chain reaction on-board Cloudbase, which will no doubt utterly destroy the aerial base, and with Scarlet drawn away by Captain Black to prevent him from saving his fellow officers, the world-security organisation known as Spectrum, is condemned to be crippled.

This episode concludes from where Captain Scarlet, Captain Blue and Lieutenant Green left the remains of the Lunarville 7 compound, where before they discovered a brand new Mysteron complex being assembled in Crater Number 101 of the Humboldt Sea, situated on the far side of the Moon. The power source will also provide Spectrum with ample oppurtunity to somehow come into direct contact with The Mysterons themselves, to try and come to a peaceful settlement. All 3 men volunteer to carry out a full-scale expedition by infiltrating the complex and removing its power source, so it won't become of any harmless use and so the Mysterons will not be able to reconstruct the whole complex after it's destruction. However, the bomb which is transported to destroy the entire complex is set for 10:00 S.E.T. instead of the agreed Midnight deadline, by a Mysteron agent, disguising himself as a technician officer of Lunarville 4, the space-base that equipped and informed the 3 Spectrum officers, in ord

The Mysterons present to Spectrum their new act of avenge; to kill one of the Angel pilots, and with Destiny on vacation, she is their apparent target, so Captains Scarlet and Blue fly to Paris to pick her up and accompany her back to Cloudbase. On the way back, 3 brand new, un-painted Angel Interceptors, reconstructed from those that were subsequently destroyed in a scorching warehouse fire, open fire upon the Spectrum personnel, but a daring dynamic and enthralling aerial dogfight between the Mysteron aircraft and the real Spectrum Angels ensures, testing Melody's Rhapsody's and Harmony's outstanding skills and training to the maximum.

A modern generation kind of tank, the Unitron – a deadly computer-assisted vehicle, is seized by the Mysterons to destroy the Supreme Commander of the Earth Forces, when he is escorted by Captain Blue to the tanks' testing range field in the Sahara desert. Two of the Commander's highest-ranking officers, Colonel Storm and Major Brooks, while en route to the SHEF headquarters, are killed in an explosive collision in a mountain-integrated tunnel, involving their car and a gasoline tanker truck, and consequently revived back to life with Mysteronised bodies. Both men are used as composers to complete the Mysteron's threat, with Major Brooks' attempt becoming unsuccessful, but Colonel Storm's turning into a life-threatening situation when accompanying the Supreme Commander to Point 783, the acting command post where the two test co-ordinators are carrying out final tests with the Unitron, but little do they know that the Mysterons have programmed the mighty formidable weapon to seek and de

A professional vault break-in duo seek out a minor Spectrum Security Vault, near the coast of New York, where ""useless"" documentation is taken, which proves quite valuable to the lawbreakers. Along with another gang member, they simulate a fake play-act for a forest lookout warden, just on the outskirts of tthe American capital, as hopeless, potentially dangerous drunks. They set-up their car with fake look alike puppets to deceive the warden into thinking that the 3 drunken men that he just warned, has helplessy crashed off the high mountaineous road, and exploded into a fireball. The gang then take care of the warden and, deliberately posing as Mysteronised humans, they announce the force's latest peril to destroy the Second National Bank of New York, however the real Mysterons have yet to announce this at all, except for stating that they will destroy ""The Heart of New York"", but Colonel White understands that the bank is more than vital to full-fill the threat, as it stocks the en

A divulged, top-secret meeting with the World President and two Spectrum Intelligence Agency officers, one of which is a general, the other a science doctor, who has created a new Mysteron electrical gun & detector following the inexplicable events with the late Doctor Magnus who attempted to kill General Tiempo, takes place in the shooting grounds of an African private game reserve. Colonel White and Captains Scarlet and Blue find themselves in a treacherous hunting sport, when the Mysterons helplessly attempt to prevent Spectrum from conducting the usage of their two brand new and innovative mobile weapons where one can kill a Mysteronised person with a strong electricity voltage, the other can distinguish and identify Mysteron characteristics within a person using normal X-Ray systems. But, unbeknown to the group of men, there security officer-in-charge, Captain Indigo, has been murdered in cold-blood by Captain Black.

A World Air Force plane, carrying Commodore Goddard and his right-hand man, and being escorted by Melody Angel, is struck by a shocking clash of thunder and lightning, and crashes, directly becoming the object to be reconstructed by the Mysterons. The force broadcasts it's current threat, that they aim to kill all 10 of the worlds' top air-chiefs, who make up the executive Supreme Command of the World Air Force, who want to discuss a plan to dissolve the war of nerves between Earth and the hostile force. They plan on doing so, by holding an International Air Conference at the loneliest location in Europe and the UK; Glen Garry Castle, in Scotland, which the Mysteronised Goddard has chosen to hold the conference to be. This is however unknown to Colonel White, who is awaiting the approval from Captain Scarlet, that the castle's security is set up and approved. After she brings the delegates to the castle, to start the conference, Symphony Angel is taken prisoner, as is Captain Scarlet,

The Frost Line Outer Defence Base Network, is endangered by the Mysterons when they destroy a maintenance truck, murdering it's engineer/driver in the process, as a cover to infiltrate the defence bases sited in Northern Canada, where the Mysteronised engineer intends to proceed in removing all oxygen from the bases' self-contained atmosphere. With bases' ""Red Deer"" and ""Carriboo"" already taken down, the next base in the ring, ""Big Bear"", is the Mysterons' final target, but if the base is attacked also, the commander-in-chief of the defence network plans to commence a vengeful missile strike on Mars, where the main Mysteron complexes are established. Colonel White desperately wants to prevent this from happening, and so, he assigns Lieutenant Green to his first off-base, ""in-the-field"" assignment, along with Captain Scarlet, to evaluate just how the bases are being cut off, and stop the maintenance engineer from triggering off a global disaster.

In the centre of London, the capital of England, a double police-escorted transporter, carrying a nuclear explosive device, built for civilian use, seemingly goes out of control, shaking of its' motor guards and its driver regaining conscience in a back alley. The transporter, now in the remote-controlled possession of the Mysterons, has been hidden in an under construction car park. Captains Scarlet and Blue are assigned to investigate the drivers' mysterious discovery, that the famous Big Ben clock struck 13 times, which may be a clue to finding the transporter, before it destroys the whole of Central London. However, the driver's founding's are more than unreliable due to his perplexed state of memory.

2068 A.D. – Captain Black, an highly-regarded senior agent of the world security organisation, Spectrum, makes an uncanny mistake while conducting a research discovery mission on Mars, trying to evaluate where a set of mysterious signals have been originating from. But while doing so, he mistakes a surveillance device for a defence weapon, when discovering a massively-scaled, futuristic complex, built and controlled by an unknown force, who specifically call themselves ""The Mysterons"". Unintentionally destroying the peaceful colony, Black is taken over by the hostile power, and from there on, will be the Mysterons' primary instrument to devise their acts of retaliation, swearing upon their declaration that they will annihilate all life on Earth and will unleash a very extensive war of nerves upon the innocent planet. To make their unveiling statement known, they plan to kill the World President, and in order to accomplish their first attack; the Mysterons cause the car which Captains S
