Hugo Bunzel, a caring father and town councillor in the tranquil town of Lieberich, is a self-confessed teetotaller and, as such, president of the Association for Combating Drunkenness. He is blindsided when he learns that he will inherit a fortune worth millions - but only on condition that he drinks three bottles of champagne a day for a month. A tough test, which Bunzel initially submits to with great reluctance, but soon becomes more and more cheerful, regardless of the entanglements around him...
