A dead man in the lake. Chief Inspector Arno Groth back at the place of his childhood. A city that has learned to remain silent. Perceptive and suspenseful until the end, Susanne Tägder shows what happens when people want to maintain their power at all costs. Inspired by a true case. Mecklenburg, early nineties: Chief Inspector Groth is sent back to his hometown after years in the West. As a reconstruction worker in the East, he is supposed to train colleagues in West German police work. He himself has had his difficulties with the regulations since his daughter died. However, he can still rely on his instincts. When the body of boat rental company Siegmar Eck is fished out of the local lake, Groth knows that it was not an accident. Why should a good swimmer like Eck drown in the lake? And that shortly after he visited Groth and claimed that he was being persecuted? The colleagues want to close the case, but Groth continues to investigate. And in the process, he comes across a lead that leads him to a waitress in the nearby restaurant and back to an unsolved murder case. New product
