High season on Usedom. Sophie Thiel has accepted a holiday job and waits tables in the café on the Heringsdorf pier. She becomes friends with her young Polish colleague Jadwiga Gryn. After work, they make their way home together on their bikes. Shortly after the girls have parted ways, Jadwiga is ambushed, drugged and kidnapped. Julia Thiel survived her serious accident and regained her strength in rehabilitation. At her own risk, Julia releases herself from the clinic and drives home. There, Karin Lossow has meanwhile taken care of Julia's husband Stefan and granddaughter Sophie. The search for the missing person is the first job that Inspector Thiel is now taking on again. Jadwiga's friend Christoph Dierwald fears the worst. Nevertheless, he takes part in a demonstration in front of the Ostseeklinik. Christoph is a radical "life protector" who protests against Polish-German "abortion tourism" on Usedom. The Polish gynecologist Malgorzata Kaminska works in the Ostseeklinik. One morning she is standing at Karin Lossow's garden fence and is looking for contact. Malgorzata was the lover of Karin Lossow's husband, whom she shot eight years ago, but she brusquely rejects Malgorzata. Nevertheless, Karin decides to visit the doctor and get involved in a conversation. Shortly thereafter, Malgorzata is found dead. Ex-prosecutor Karin Lossow comes under suspicion. Julia and her mother must once again face the darkest moment in their family history.
