Out of love for a beautiful passenger he met on a crossing, journalist Robert Vitrac agrees to deliver a letter to a man named Pablo. A dangerous mission, since the beautiful Manuela has had in her possession the proceeds of a robbery, which she must forward to the fence. In this game, Vitrac would lose his honor and perhaps his life if Inspector Berio's friendship didn't protect him. Manuela, who seemed sincerely in love with the journalist, falls victim to the bandits.

The fictionalized life, and interpreted by himself, of the popular boxing champion Marcel Cerdan. Training sessions, matches, victories, flight to the U.S.A. where the title of world champion is disputed, form the whole subject of the film.

Everyone in Paris thinks Fantomas is dead. A wave of extortion, blackmail and murder all point to the master criminal. Inspector Juve and his reporter friend Fandor set out to find the truth.

Patrica is the wife of Alain de Saulieu, a handsome engineer. She unfortunately loses her husband, who is killed in action during a battle of the First World War. At least, this is only the official truth, for Alain is not dead. Patricia indeed recognizes him one day. But the inverse does not work the other way around: Alain has become amnesiac and he does not remember her. And worst of all, he lives in a conjugal relationship with Germaine, his dedicated nurse, who is now pregnant by him. What has the future in store then for the three (not to say four) of them?
