It is by no coincidence that Emma (22, medical student) has taken the job as the nightwatch in the forensic department. She grew up with her mother, Kalinka, who committed suicide when Emma was 10, and her traumatized apathetic father, Martin. The fatal night the psychopathic inspector Wörmer almost killed Emma's parents before they were saved at the very last minute by their friend Jens marked the family and left a suppressed and unspoken fraction of her parents' past. Since that night they have all been haunted by the memory of the monster, and as a result Emma has been brought up in the suppressed memory, and remaining silence after the event.

Emma decides to investigate what happened in her parents’ past. Upon meeting with Wörmer, Emma wakes him from his coma, and unintentionally initiates a bloody revenge on all of those who sealed Wörmer’s destiny. Emma and Martin are now surrounded by vindictive maniacs whose only motive is revenge.
