A young man picks up a girl at a disco (this is supposed to be set in London although the film is Italian) and takes her back to his uncle's country farmhouse for some nookie. There, they are interuppted by a man who murders the servant and keeps them hostage. The hero's uncle is a judge (Fernando Rey)and he sends a cop to investigate but the cop (played by Frank Wolff) turns out to be in league with the hostage taker and is in fact a man that the uncle sent to prison and is after revenge. He's also after something hidden in the house but we're never quite sure what.
Tedious and boring, poorly dubbed and ridiculously scripted - this is not a horror film and certainly not a giallo either. There's also practically no sex and violence despite the Redemption promises. The main problem is that there seems to be no point in the whole hostage saga at all since Wolffe has already planted a bomb in Rey's office. A number of convoluted plot twists are gradually revealed but the fact is nobody really knows what's going on here and the thing is padded out about twice as long as it should have been.
