At the crime scene of murdered doctor Kai Wülker, the trail leads to a cold case: intact DNA of Jessica Sonntag, who has been missing for more than 15 years. Detectives Katrin König and Melly Böwe confront Jessica's family with this disturbing news, which is received differently by all family members. Evelyn Sonntag, a deeply saddened woman, has always believed that her daughter is still alive. The father, Robert Sonntag, hoped above all that his daughter would at least die quickly. He is shocked that hope and fear are starting all over again.
