Danny de Donder arrives home prepared to spend a peaceful night. He has not allowed for the antics of his philandering partner, Rudy de Roeper, who has not only been using Fogg's name in his affair with the sexy Mrs. Vossen, but also borrowing his car. When the car is stolen a frantic chain of events is set in motion involving the over-inquisitive Inspector Brandy, and Rudy's wife and mistress - both called Conny-and what follows is an hysterical nightmare of confusion.
