"Cornforth" (Griffiths Jones) wakes up, fully clothed, in a strange house in the middle of nowhere. He has no idea how he got there, nor why he has a gun in his hand and why... wait for it... there is a corpse in the kitchen. To add to his confusion, he is joined by two rain-soaked backpackers - "Jean" (Patricia Laffan) and "Marian" (Maya Koumani). When they discover his secret they try to skedaddle only to be prevented from doing so by their befuddled host. What now ensues is really a rather daft murder mystery that involves him and the now somewhat miraculously convinced "Jean" returning to London where they try to get to the bottom of this increasingly far-fetched conundrum. It is pretty obvious - once we are back in civilisation and amongst a cast that includes the usually reliable Bruce Seton and the plummy, easy on the eye, James Kenney - who is behind the crime, even though the motive remains curiously elusive right until the last few scenes. It's not the worst, it's clearly just a job of work for all concerned with an unremarkable script and some equally forgettable performances that passes an hour or so, but not in any way remotely memorable.
