Two men are stranded at the bottom of a well. One, with a serious injury to his head, thinks his has fallen in is own back garden in present-day Britain. But the other tells him they are really prisoners in a medieval dungeon. Who is right, and where are they really?

This is the epic story of a B-24 'Liberator' bomber aircraft called 'Shady Lady', that took off from Darwin, Australia, on Friday, 13th August 1943, on what was at that time, the world's longest ever attempted bombing mission.

Seven people and their desperate search for escape, only one will survive. The last performance of a pantomime is held at an old, isolated theater in provincial England. The show has been a disaster, attracting only a handful of locals. The final party afterwards turns out even worse and some of the cast and crew slip away for their own private session in the creepy basement. Amongst the group are the enviable pantomime leads and real-life lovers Clarice and Nathan, currently not speaking, the womanizing director Derrick and the thirty-something, obscure stage assistant Janet. As their bash kicks off Derrick disappears, only to be found with his throat savagely slashed. When they discover that they're locked in the next victim dies. The killing continues. Paranoia grows. Nobody can be trusted.
