Heini Schoch becomes a millionaire on his birthday of all days. He mistakes his briefcase for a completely identical item. With one tiny difference: the other suitcase is stuffed with bundles of money. This money can only come from a scam, Heini concludes in a flash, nobody carries that much cash around with them. So there is very little chance that the police will be called. Heini tells his confused wife Hedy to pack her bags. They are to take the next plane out of the country so that the crooks don't find out about them. But Heini has rejoiced too soon: suddenly the police knock on the door and ask lots of "stupid" questions. Luckily, Heini's loyal friend Viktor is there to help - albeit very reluctantly. In order to distract the police, the two of them build a huge house of lies. Eventually it all comes crashing down.
