This is a wet dream of a film for the conspiracy theorists amongst us! "Ewan" (Amit Shah) and his wife "Silke" (Sura Dohnke) are holed up in a rather nice lakeside house in Flanders. They are awaiting the arrival of a journalist to whom they are going to impart some fairly startling information - for a fee, of course. It's so significant that the newspaper sends two minders - "Glynn" (Roger Evans) and "Chris" (Tom Burke) to keep an eye on them. Now these two have worked together for quite a while, but the latter man is eyeing up a career move to the middle east - and he's not necessarily looking to take his mate with him. Over the next 24 hours of their incarceration, we learn a little of the characteristics of these four flawed individuals, and perhaps those who can lip-read might get a clue as to the nature of the big secret! The arrival of foul-mouthed junior journalist "Flo" gives Jenna Coleman a couple of scenes to brings things to an head and deliver a quirky denouement to this lightly, but darkly, comedic shorter drama. For me, the stars are an on-form Evans who delivers well as the Welshman with a few demons to deal with, and Shah who plays the hapless IT geek who takes paranoia to an whole new level. Apparently the title means "bell ringer"! Nope, me neither... It's enjoyable, though.
