Efforts to move Britain into the modern age don't sit well with the people of the small village of Anderia Marsh, who have claimed a right (going back to Henry III) to evade government-imposed import duties and taxes. And when the government decides to curb this right, the whole village quietly rises up in a comical rebellion. After their vessel runs aground during a storm and is impounded by the British authorities, local smugglers must find a way of disposing of their contraband brandy cargo before it's discovered by the Customs Officers.

Entirely silent, with a musical score, sound effects and incoherent mutterings, the story revolves around a weekend gathering at the decaying country home of the eccentric and lewd General Futtock (Ronnie Barker) and the series of saucy mishaps between the staff (Michael Hordern plays the lecherous butler) and his guests.

Set in the India of the British Raj, the evil and untrustworthy Prince Guhl (Raymond Massey) plans to wipe out the British troops as they enjoy the hospitality of Guhl's spacious palace. It's up to the loyal young Prince Azim (Sabu) to warn the troops of Guhl's treachery by tapping out a message on his drum.
