“Guess what we’re doing! We’re going to practice swimming.” Hanan accompanies her brother to classes in the public pool. The first swimming badge is called the Seahorse, their instructor explains, because it “stands” in the water and doesn’t drown. When Hanan’s family came to Europe in a rubber dinghy, she couldn’t swim. To forget this experience, she learned not to go under in the water – like a seahorse.

A voice from nowhere proclaims life instructions: “Take a deep breath, say YEEES! … and stop being boring!” But rules and authority gradually elude the anonymous instructor. He becomes a chattering, contradictory flâneur through the universe of his problem-fraught private affairs. Those therapy units have a really sneaky design.

Katharina’s father used to work for the GDR secret service. In the mid-1990s he was arrested for a murder ordered in connection with his former job … and released. Ever since then, Katharina has feared that the doubts about her father’s innocence might throw a shadow on her life, too. A film about family secrets and the question whether some things hadn’t better remain hidden.
