Noël, a former gangster now breeding horses on his large estate outside Paris with his beautiful wife Nicole, has his quiet life turned upside down when two wanted crooks arrive in a stolen car. One is an old accomplice called Serge, fatally shot, while the other is a young psychotic called Mickey. When Serge dies, Noël buries him. Mickey goes into Paris and on his return finds two police detectives, Bonnardot and Sarlat, at Noël's house. After threatening them, he escapes and holes up with Dany, a friend in Paris.
