Two young women, Margaret and Lisa, are set to take the overnight train from Munich in Germany to stay with Lisa's parents in Italy for Christmas. Unfortunately a pair of psychotic hoodlums and an equally demented nymphomaniac woman terrorize the pair.
Sadistic no-count killer Nanni Vitali and three other equally brutish hoodlums escape from prison. The foul foursome embark on a savage rape, murder, and robbery spree. Vitali even abducts and defiles frightened hapless lass Giuliana Caroli. Meanwhile, rugged police inspector Giulio Santini is determined to bag the despicable Vitali.
Giulio is a young boy who still does not know which path to take in life, his father puts him in his place in the bank, but he's too lazy to accept. In fact, he lives with his friend Max and they just pick up and exchange women. One day during a photo shoot in London, Max meets a girl, Dora who is going to change their lives.
