A rather baffling murder mystery. A skull is found in an alleyway between two houses, a man thought to have been killed some time before. Inspector Carr (John Hamilton) and Doctor Crabtree (Donald Meek) first interrogate the eccentric inhabitants of the one house, the Beck family (Harry Mestayer, Paul Guilfoye and Joanna Roos) who seem to be performing various strange scientific experiments and acting very strangely. In the other house is Chinese merchant Wang Run (Lee Tong Foo) who conveniently was away when it is thought the murder took place, he also has a number of rather sharp Oriental weapons...
Crabtree comes up with an ingenious way to try and scare a confession out of either suspect (the fact it could have been someone else entirely is somewhat overlooked). However, things come to a head when the Beck family try and do a runner and a groaning man is found in their attic...
A short feature which proceeds at a breakneck pace, unfortunately a little too quickly as much remains unexplained, for example what exactly were the Becks up to?! A fairly interesting if not especially that good crime film.
