Green Grow the Rushes.

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.
