Elevator to the Gallows

A beautiful woman, Florence, and her lover, Julien, plan to murder her husband (who happens to be Julien's boss as well), so they can be together. After carefully carrying out the crime, Julien gets stuck inside the elevator when the power is turned off. The film takes off in a number of surprising twists and turns, one of which includes a young couple who steal Julien's car. They take a ride outside the city and kill a German couple in a hotel, a crime the police eventually pin on Julien. (official distributor synopsis)
