The action begins with bachelor Jimmy Pitt in New York; having fallen in love on a transatlantic liner, he befriends a small-time burglar and breaks into a police captain's house as a result of a bet. The cast of characters head to England, and from there on it is a typically Wodehousean romantic story, set at the stately Dreever Castle, overflowing with imposters, detectives, crooks, scheming lovers and conniving aunts. Great fun!
