Le Joli Cœur.

Frank and Bernard share the same apartment and both work in the same tourist agency. Bernard drives the coach through the streets of Paris and Frank is the guide. The driver longs for a family life but he is not lucky with girls. So he asks his friend, who is a womanizer, to help him find at last his better half. Frank winds up in a hospital and falls for the shrink, Nina. Faithful to his pal, Frank comes to his rescue but he falls in love with Nina too.
