Night Train Murders

Two young girls, Lisa and Margaret, coming home for Christmas, make the acquaintance of Blackie and Curly, two thugs. Blackie has already seduced a widow in the train and, soon, the five protagonists decide to share the same compartment.

After a while, Curly, who’s on drugs, starts to harass the girls, hits them and finally rapes Lisa with a knife. Margaret escapes from the compartment and jumps from the train only to die on the rocks beneath the railroad line. Then, the three criminals throw Lisa’s body out of the compartment’s widow.
When they arrive to their final destination, they manage to be invited by Lisa’s parents, Giulio and Laura Stradi, who are still waiting for their daughter. Giulio Stradi listens to the radio and understands that his guests are murderers. He decides to take the law into his own hands. —Allwatchers.com
