Mister Roberts

A German spy who is a dead ringer for the Captain is planted on the ship.

Seaman Herbert Miller's arrival is highly anticipated as he is the first Navy classified cook to serve aboard the Reluctant, except he can't cook. Miller has been reassigned so many times Roberts allows him to stay, thinking he, Pulver and Doc can help him learn to cook. Captain Morton invites Admiral Morrison over for a meal. Roberts, Pulver and Doc cook it, giving Miller the credit who is immediately transferred by the Admiral to his flag ship. D'Angelo tells Roberts that Miller learned to be a signalman on his own so they send a recipe with cooking details to Miller on the flagship. Harry and George, the crew of a Japanese two man submarine, intercept the recipe and think they have stumbled on to a new code. Roberts spots the sub periscope, flashes a new recipe ""Sukiyaki Underwater"" and Miller informs Admiral Morrison who requests a patrol bomber.

The crew returns to the island of Namu to take a survival test.

The ship must transfer three USO girls and the Captain orders them to stay out of sight. The Captain ends up in sick bay which leaves Mr. Roberts in charge. Ensign Pulver gets permission for the girls to do their act for the crew. Roberts spots the periscope of a two-man Japanese submarine that is watching the girls do their show and tells Pulver to ""keep those girls dancing"" until the patrol bomber he requested arrives.

Doc must gain the favor of Beulah Cronk, the lady who owns an island on which the Navy wants to place observation posts.

The Reluctant has orders to make contact and maintain good relations with the natives of Namu atoll whose young men were taken away by the Japanese. Captain Morton angrily orders them off the ship but then sends Roberts, Doc and Pulver to make amends. Doc and Roberts treat the Chief's stomach ailment with the last bottle of Captain Morton's medicine, which the Chief keeps. Pulver brought trinkets to trade with the natives and ends up engaged to eight girls.

Captain Morton is visiting Admiral Wetherby. Mr. Roberts, Doc and most of the crew is on liberty, so that leaves Pulver in charge of the Reluctant. He gives medical supplies to a pretty lieutenant without permission. Roberts refuses to help him get them back until he finds out Pulver signed his name. They track the pretty lieutenant down but are not sure if she's trying to trap Tiki Sam or is working with him.

Captain Morton puts Doc and Roberts in charge of his ailing palm tree, an outstanding cargo achievement award from the Admiral. They discover Pulver has been feeding it hot creamed chipped beef. Seaman Insigna has received a Dear John letter from Alice, a red cross worker on Cocoa Island. In order to meet Alice's sexy co-worker Rosemary Pulver tells the Captain there is a plant doctor on Cocoa Island. Roberts goes along to talk to Alice concerning Insigna.

Roberts's transfer finally comes through, but the Captain plans to block it.

The Captain asks for Roberts' help in creating a cover story to cover-up the fact that the crew screwed up a mission.

Mr. Roberts orders a reduction gear installed for the Reluctant which will give it the speed it needs to allow it to join a convoy headed to combat. The new part causes some damage which at first is misinterpreted as being hit by the enemy. The gun crew directed by Ensign Pulver shoots down their radio tower while firing at a zero. This limits the Reluctant to receiving messages. Morton is ready to court martial Roberts until he hears a radio message that the Reluctant is presumed lost after taking a hit from a Japanese sub. The convoy was able to sink the sub and Morton and the Reluctant are considered heroes for leading it away from the convoy.

Captain Morton forces the crew to watch the same movie ""The Crawling Glob With the Bedroom Eyes"" every night even through musical with girls in bathing suits is available. Roberts intervenes unsuccessfully to have the musical shown until he learns it's the Captain's birthday. In an attempt to soften him up Roberts gets the crew to throw the Captain a party, complete with a fake gold watch from Pulver. Using the watch Roberts coerces the Captain into showing the musical and throwing the Glob movie out his porthole, where Pulver is waiting with a net. Which movie will they see?

The Captain is in an unusually good mood and is granting all sections liberty when they dock in Azalia. Pulver, Roberts and Doc discover Captain Morton is in love with a woman named Leona. Manion and Cookie trail the Captain intent on getting some blackmail pictures. When Morton calls on Leona she isn't home and then he sees her in a bar - with Roberts!

Roberts is stunned to find that a beautiful woman is part of the cargo he is suppose to load on board.

The Captain sinks a washtub planted by Pulver thinking it was a Japanese submarine.
