Bill Harper and Petronilla Brand are a young couple that, through a series of mishaps and accidents, get unintentionally involved in a brandy-smuggling (from France) racket. Because of an accidental sinking of Tony Rackham`s boat, Bill and Patricia take him across the Channel on their boat which, to their dismay, is soon filled with several kegs of brandy. It then evolves into a series of intentional and unintentional dodges trying to evade the Customs officials.
