A young woman is murdered and robbed in broad daylight. A young man is arrested, in possession of some of the jewels of the victim. The passionate protests of his sister arouse the compassion of Za la Mort, who promises to help the girl.

A young student of an upper-class background who is surrounded by classmates that are of working-class backgrounds, after a novel in diary format by Enrico Bottini.

The title of this Italian melodrama translates to Pact with the Devil. However, His Satanic Majesty does not appear in the film. Rather, this expensively produced period piece is more along the lines of Romeo and Juliet, with young love threatened by warring families. In his first Italian film, Hollywood veteran Eduardo Cianelli goes through his usual villainous paces as the scheming father of the male lead (Jacques Francois). The most fascinating performance is rendered by Umberto Spadaro, as the village idiot, or is he? Patto col Diavolo makes the most of the visual dynamics of Italy's mountainous Calabrian region.
