Four witnesses, one truth. However, all of a sudden no one wants to have seen anything. The young lawyer Jessica Mauer (Sonja Gerhardt) takes on a seemingly clear case: In broad daylight, two teenagers provoke a young woman (Stephanie Amarell) in front of the eyes of numerous passengers in the tram and beat up her dark-skinned boyfriend (Julius Dombrink). They beat him up so bad that the male victim falls into a coma. The police are able to arrest the two perpetrators while they are still at the scene. But suddenly, according to witnesses, the case is no longer so clear-cut: the couple Gerd (Oliver Bröcker) and Doro (Pia-Micaela Barucki) disagree about what they saw and what they should tell. The 24-year-old drugstore saleswoman Nicole (Mira Elisa Goeres) retracts her statement and doesn't want to remember anything. At the same time, her ill (cancer) mother (Gabi Herz) can suddenly afford expensive treatments. And pensioner Hans Armbruster (Holger Franke) finds his beloved dog dead in the garden and then questions everything he had previously reported as a witness. There are no more incriminating statements against the accused perpetrators Kevin (Maximilian Beck) and Mike (Béla Gabor Lenz). Can Jessica still hold the perpetrators responsible? Or is the fear of the four witnesses in the end more powerful than their conscience?
