A film company on location happens to photograph a murder in progress. Ambitious police inspector Bernard (Michel Simon) hopes to advance his career by nabbing the culprit. Unfortunately for Bernard, the murderer closely resembles a set of identical twins! Once Simon finally figures out who's who, a gang of criminals, angered at all the publicity engendered by the case, fix it so that both the criminal and the inspector lose out in the end. A very minor piece, Les Trois Font la Paire (Three Make a Pair) is historically important as the last directorial effort of Sacha Guitry, who died 14 days after the film's premiere.
