After twenty unsuccessful years, pop singer Harry Kuntz has landed a hit: a remake of Lehár's "Your is my whole heart" catapulted him to the top of the charts. While Harry basks in his sudden fame, his brother and manager Tommy's dream of wealth is just around the corner. A car breakdown on a stormy night leads the brothers to a remote house. Harry is once again playing the sexual daredevil and thinks he's having success with his pick-me-up. A fatal error. Suddenly, the two brothers find themselves in a nightmare from which there is no escape.
Unfortunately the movie Stille Wasser is not yet available on HBO Max.
