Once again this season shows the strong cohesion of the PK 14 team. Nils Sanchez (Enrique Fiß) is suspected of having lost control of himself while visiting a club at night. Of all people, he is said to have smashed furniture and assaulted a woman - but unfortunately the investigator remembers nothing. His partner Harry Möller (Maria Ketikidou) firmly believes in Nil's innocence and does everything to prove it. Bente Hinrichs (Sinha Melina Gierke) also stands by Lukas Petersen (Patrick Abozen) when he loses his service weapon during a life-saving mission. And on a Friday the 13th, of all days. Despite her cool manner, the head of the police station, Mrs Küppers (Saskia Fischer), keeps things together and maintains her inimitable dry sense of humour in almost every life and police situation.
