A death in Bremen's student scene keeps detectives Liv Moormann (Jasna Fritzi Bauer) and Linda Selb (Luise Wolfram) busy, assisted by their colleague Patrice Schipper (Tijan Njie) from the KDD (Criminal Investigation Department). As the investigation unfolds, an abyss of loneliness, overwhelm, and dashed hopes opens up. Law student Annalena Höpken (Annika Gräslund) is found dead near a nightclub in the morning. She was apparently pushed down a flight of stairs and died of a broken neck. Initial investigations indicate that she had been involved in serious arguments with her roommates (Shirin Eissa, Mitja Over, Joyce Sanhá, Michael Schweisser). Furthermore, Emil Klaßen (Robin Bongarts), a homeless man who attacked Selb and is carrying the deceased woman's cell phone, becomes a suspect. It turns out that Annalena Höpken suffered from immense performance pressure, which she tried to compensate for with stimulants.
