The Thirst for Gold (1993)

Urbain and his grandmother are stingy. They buy gold with all their money, and hide it inside the bricks of a wall at their country house. Jackes, his chauffer, and his lover (who casualy is the Urbain’s wife) don’t know this fact and think they have the money hidden somewhere. When Urbain and his grandmother decide to transport the gold (with the house!) to Switzerland, in order to pay less tax, a crazy chase begins.
