The painters Teddy and Peter are great friends. They work together, they party together and they share almost everything else. It's only when it comes to giving a customer a special helping hand that they prefer to do it alone - and that happens frequently. Teddy has a few problems in bed with his wife Manuela, which is why Peter offers his help. Together they come up with an ingenious plan. But they don't know that Manuela and Peter's wife Uschi have a close friendship - the two of them have also hatched a plan.
