The Killer Must Kill Again

The Killer Must Kill Again (Italian: L'assassino è costretto ad uccidere ancora) is a 1975 Italian giallo film directed by Luigi Cozzi. Cozzi originally wanted to call the film Il Ragno (The Spider) but it was changed to The Killer Must Kill Again by the producers. It is based on the novel Al mare con la ragazza (translation: By the Sea With the Girl) by Giorgio Scerbanenco. The film was also released as The Dark Is Death's Friend. Michel Antoine (who plays the killer in this film) later played the tortured painter in Lucio Fulci's The Beyond.

Plot
Giorgio is a greedy adulterer who makes a deal with a serial killer (Michel Antoine) to dispose of his wealthy wife, Nora. Unfortunately, a thrill-seeking young couple steal the killer's car with Nora's corpse in the trunk, ending up at a run-down seaside villa. The killer follows their trail and eventually finds them, violently raping the young girl when he finds her alone, then he knocks our her boyfriend upon his return. Now the young girl is left to fend for herself against the merciless killer.
