Bodybuilder Tarim Kosic is murdered in a Ludwigshafen parking garage. When examining his DNA, it turns out that Kosic was the alleged perpetrator in a rape case a few weeks ago. The young dancer Marie Rainers was injured so badly that she has been in a coma ever since. Day and night her mother Birte sits desperately at the sickbed - is it conceivable that in her pain she became a murderer out of revenge? Lena Odenthal, Mario Kopper and Johanna Sternbut also get on the trail of the young rapper Yago Torres. He claims to be in love with Marie, but has not succeeded, as reported by her friend Evelyn. Does he come into question as the perpetrator because he wanted to prove his love? When Lena Odenthal and her team find out that Kosic's buddy Daniel Peters was also involved in the rape, they hope to get further with his help. But when Kopper and Johanna interrogate Stern Peters, he collapses and dies.
