A bomb explodes in a busy square, killing five people. LKA investigator Helen Dorn (Anna Loos), who was on the scene to meet a man, is among the injured and is hospitalized with blast trauma. A terrorist background is likely, as shortly afterwards a confessor’s video appears on the net.
Based on the evidence, the perpetrator responsible for the deaths of five people in a park seems to be quickly identified: Ron Keller, a converted Islamist. When the SEK raids his workshop, Ron Keller is shot dead. The case seems watertight: a mentally disturbed assassin, an indiscriminate selection of victims, a quick investigation and arrest.
Only Helen Dorn does not believe in this simple solution. Instead, she suspects Adrian (Marcus Mittermeier), the man who lured her to the square and with whom she had a one-night stand. Helen interferes in the investigation of her colleague Renko (Adnan Maral) from the State Security – without telling him about her suspicions. She researches the victims. And comes across the address of the correctional facility in a calendar entry of one of them, the terminally ill ex-policeman Kaminsky, who worked as a security guard for a small jewelry store on the square. The inmate, of all people, whom Kaminsky has visited several times recently, escaped from the institution on the night of the attack: Khalid (Murathan Muslu), a Lebanese drug dealer and convicted murderer.
Helen begins to suspect that the bombing was by no means random, but was merely a cover-up for a murder. She gets deeper and deeper into a wasps’ nest of roped-in civilian investigators Mertens (Armin Rohde), Kurth (Rainer Strecker), Ahlsen (Timo Jacobs) and a crime committed long ago. Meanwhile, the escaped Khalid tries to prove his innocence from back then.
In parallel, Adrian does not stop stalking Helen. The nightmare of a subtle stalking takes its course. No one can help Helen, and even in the LKA, with Mattheissen (Daniel Friedrich) she comes under more and more pressure when she does not stop suspecting veteran colleagues.
