In the Folds of the Flesh

An escaped convict named Pascal Gorriot happens to witness an attractive woman named Lucille disposing of her second husband Andre's corpse at sea.

Thirteen years later, Andre's cousin shows up at Lucille's villa and he is stabbed to death by Andre's son (Colin) and daughter (Falaise) who are still living there with their mom. They even kill his pet dog who arrived with him. Soon after, another friend of the family moves into the villa and seduces the nutty Falaise, who decapitates him afterwards.

The escaped convict returns to the scene, down on his luck, and decides to blackmail Lucille for murdering her husband years earlier. He winds up in an acid bath.

The police investigate the chain of murders going on at the villa. The film even has a brief flashback to a WW2 Nazi death camp, scenes from which were used exploitatvely in the sleeve design of the British Redemption video release.
