Cocky son of a doctor Henry (Pierre Mingand), a frankly wreckless driver, has the keys to his father's car taken away from him. Even with his Maurice Chevalier impression he is unlikely to be able to impress the girls by bus. He is tempted to steal a car in order to fulfil a date, is hijacked by a real car-stealing gang and throws in his lot with them. And so we find ourselves in what I think is called a Straßenfilm - Henry rejects his comfortable background for Paris's streets of crime.
The gang at work are entertaining, with cravate cleptomaniac Jean, and le Zèbre who keeps turning up with a string of old bangers. It's good to see a black actor (Gaby Héritier) shown as part of the city's makeup, and Michel Duran is excellent as the gang's wily boss.
In this film Danielle Darrieux (still only sixteen or seventeen) escapes her role as the ballroom-frequenting daughter of the aristocracy. She is funny as the gang's honey-trap and hilarious as the sullen secretary.
There are clunky but exciting night-time chase scenes through French villages as the plot moves into something more like a road-trip movie, and there's a noticeable change in mood as Darrieux and Mingand find themselves walking down the mountain road. Here, for a while, you get the feeling of two real people talking to each other and just the hint of a different movie again.
Certainly it's an uneven sort of film in tone but still a good watch and of interest to fans of Darrieux and of Wilder.
