Dr. Loiseau organizes bizarre screenings in a tent, assisted by a carnival barker, a hunchbacked nurse, a disgraced wrestler, and an ex-convict. Together, they devise ways to attract women by leading them to believe that the doctor knows the miracle cure for cervical and breast cancer.

Denounced by a rival doctor, Dr. Loiseau is once again being pursued by the husbands of the women he kidnapped. He therefore instructs his son Victor to honor his appointments. Victor must meet Emir Azmir Krabouk, a criminal specializing in white slavery, on a sailboat. Jacques Ladrier, one of the husbands and a wealthy oil industrialist, is about to marry Angèle Jaucaut, his newly freed fiancée. Dr. Loiseau takes advantage of the ceremony to kidnap a few more women...

The husbands set out in search of their wives, who have been kidnapped by Doctor Loiseau and his accomplices. The latter is hiding in a secret hideout. Still assisted by Irene the hunchback, the charlatan doctor leads a team of workers tasked with producing bottles of the precious miracle elixir 'Force Unie'.
