Lukas Geier’s past catches up with him when the alleged killer of his friend Frank Becker asks to be placed in witness protection. Roland Büttner is a former hitman for the ‘Ndrangheta who is now a target himself. The only people he can trust are Geier and Annemarie Papst. A race against time begins when questions arise about Büttner’s true intentions and a possible mole in the criminal investigation team. Meanwhile, Geier’s partner Lara Schnee is considering selling her hotel, but receives a death threat when she changes her mind. Geier and Franziska Conte work hard to uncover the truth – but they may be too late.
