Karin Lossow meets Gerda Kolping while walking on the beach with her dog Lucky. Like every morning before work, she plunges into the cold waters of the Baltic Sea in her wetsuit. At first, everything seems normal, until Karin suddenly hears cries for help. Gerda Kolping can no longer keep her head above water. Karin still tries to pull her out of the water, but any help comes too late. A shock for their daughter Emma, who is only 14 years old - especially since her father Markus Kolping has become a nursing case since a corona infection.
