1961 film

Deuxième court métrage d'Yves Robert, sous la direction de Claude Sautet, dans lequel Fernand Raynaud, comique star de l'époque, se met en scène dans une aventure inspirée de ses sketches.

Fernand, a simple employee at the Prefecture of Police, must serve as a "sheep" to extract confessions from a leader of organized crime, who has recently been in prison. But he managed to escape by taking Fernand hostage.

Shy, timorous bank clerk, Fernand Jérôme, prevents -unwillingly of course - a gang led by "Le Grand J" from robbing the "Crédit Populaire", where he works. Having become a hero out of the blue, this new status allows him to woo Renée, the daughter of chief inspector Merlerin. What Merlerin does not know is that the man he has been trying to arrest for years, "Le Grand J" is in fact Joseph Jérôme, Fernand's father, who has disappeared for years...
