Ascenseur pour l'échafaud
Florence Carala and Julien Tavernier are lovers who plan to kill Florence's husband, Simon Carala, a wealthy industrialist who is also Julien's boss. Julien is an ex-Foreign Legion parachutist officer and a veteran of the Indochina and Algeria wars. After working late on a Saturday, with a rope he climbs up one storey on the outside of the office building, shoots Carala in his office without being seen, arranges the room to make it look like a suicide, and then makes his way out to the street. As he gets into his Chevrolet convertible outside, he glances up and sees his rope still hanging from the building. Leaving the engine running, he rushes back and jumps into the elevator. As it ascends, the caretaker switches off the power and locks up the building for the weekend. Julien is trapped between floors.
Moments later, Julien's car is stolen by a young couple, small-time crook Louis and flower shop assistant Véronique. Florence, who is waiting for Julien at a café nearby, sees the car go past with Véronique leaning out of the window. She assumes that Julien has run off with her and wanders the Paris streets despondently all night asking for him in the bars and clubs where he is known. While joy-riding, Louis puts on Julien's coat and gloves. Checking into a country motel, the two register under the name "Mr. and Mrs. Julien Tavernier" to avoid problems for Louis, who is wanted for petty crimes. At the motel, they make the acquaintance of Horst Bencker and his wife Frieda, a jovial German couple on holiday with whom they had raced en route to the motel. After Frieda takes pictures of Louis and her husband with Julien's camera, Véronique takes the film to a photo lab beside the motel for developing.
After the Benckers go to bed, Louis attempts to steal their Mercedes-Benz 300 SL gullwing. Bencker catches Louis and threatens him with what appears to be a gun, though it is really a cigar tube. Louis shoots and kills the couple with Julien's handgun. He and Véronique return to Paris and hide out in her flat. Convinced that the crime will be traced to them, Véronique persuades Louis to join her in a suicide pact. They take an overdose of pills and pass out.
The Benckers' bodies are discovered, along with Julien's car, handgun, and raincoat. Julien therefore becomes the prime suspect in their murders, and the morning newspapers print his picture. Searching for him, the police arrive at the office building with the caretaker, who unlocks the entrance doors and switches on the power. The elevator is working once more and Julien is able to escape without being seen, but when he orders coffee and croissants in a café he is recognized and the police are called to arrest him. In the office building, the police discover Carala's body but assume he committed suicide. However they charge Julien with killing the Benckers, refusing to believe his alibi of being stuck in an elevator.
Florence is determined to clear him and sets out to find Véronique. She and Louis, their suicide attempt having failed, are alive but drowsy. Florence accuses them of killing the Benckers and goes off to call the police. Louis at first thinks there is no evidence to connect him with the crime, but then remembers the photographs of him with Bencker. Rushing off to the photo lab, he finds that the police have developed the pictures and he is arrested.
Florence has followed him and, when she enters the lab, the police show her the photographs taken with Julien's camera. These make clear that she and Julien were secret lovers, who shared a motive for killing her husband. Both will go on trial for Carala's murder.
