Watch on HDtoday. Peter Hannemann is a married man—and an exceptionally sleepy individual—who owns a nearly bankrupt sleeping-pill factory in Berlin. His twin brother, the bachelor Paul, runs the lucrative winter sports hotel "Helvetia." Paul is the complete opposite of Peter and is full of temperament. The millionaire Hardegg, arriving from Buenos Aires with his daughter Ines, buys the hotel—which is fully booked at the time—and evicts Paul. Paul travels to Berlin, but Ines has already fallen in love with him. Numerous complications ensue.
