Eric Seeler (Ströbel), a former police officer now working as a streetworker, lives with his stray dog Gwena between the youth center, the shipyard, and everyday reality. Hannah Vogt (Linke), on the other hand, is rational, controlled – and devoted to regulations. When one of the youths from Seeler’s project comes under suspicion of murder, their worlds collide. But as the investigation intensifies, confrontation gives way to trust – and opposites grow into a team.
