Jockey Jack has a bill open with a gangster just released from jail. He somehow manages to parry the gangster's knife attack backstage at a theatre and the latter ends up dead being put into a double bass case. A day later the gangster mysteriously has disappeared, but it turns out that he was carrying a bet ticket for a horse race now worth over a million. A turbulent run for the money begins.

The story centers around a graduating class of "less-gifted" students in a private Versailles high school. Only a miracle has brought the students this far along, and after a practical joke misfires and the whole school is dynamited, the students are in deep trouble. They have to present themselves in court for their punishment and it could not be worse: If they don't pass their high-school graduation exams, they go to prison!
