Anne is a swimming coach and talent scout. Full of enthusiasm she trains her niece Julie for the state championship. That's why she often clashes with her sister Miriam. Miriam believes that her daughter is overwhelmed by Anne because she gave up her swimming career many years ago under unclear circumstances. On her mother Inge's 65th birthday, there was another argument. Apparently there's a long-kept family secret that's now threatening to surface. Anne's father tries to calm things down, but Anne leaves the party. A short time later, she is afflicted by a panic attack: she thinks she sees a shadow at the bottom of the swimming pool. The same thing happened to her many years ago when she suddenly lost her orientation during the decisive swimming competition. Anne wants to know what's behind her fears.
