When the sculptor Annette Baer finds her adult son Lucas with bloody hands in the bathroom of their shared apartment at night, she knows that something terrible has happened - even if Lucas claims to have done nothing. The next morning, inspectors Anna Janneke and Paul Brix are called to the body of young Cara Mauersberger. Cara came from the small Saxon town of Döbeln and had only moved to Frankfurt a few months ago. Leon Hamann, a property management employee, discovered the dead woman. The knife wounds in Cara's body indicate an emotional act, the smashed balcony door indicates a break-in. But Hamann, who has apparently been watching Cara closely, knows that the dead woman had an argument with her boyfriend the day before. So it doesn't take long until Janneke and Brix find a connection between Cara and Lucas Baer. Annette Baer manages to divert the focus of the police investigation from her son. Instead, the commissioners discover that Cara was a gamer in her free time and commented live on her games on a streaming platform under the pseudonym Chipmunk. The fact that she openly refused sexist depictions did not only earn her goodwill in the male-dominated scene. Her follower CancelChipmunk, who pursues an aggressive, ideologically colored agenda online, is targeted by the commissioners. Is Lucas, who like his mother very talented artistically, who wanted to develop a game design with Cara? Just as Janneke and Brix discover CancelChipmunk's identity, psychology student Denise is also found murdered.
