A passerby calls a ambulance, too late, while nurse Nicole Sammer tries to reanimate in vain Ralf Weller why died from electrocution, possibly only fatal due to a cardiac condition. He occasionally worked as luxury call-boy in Tanja Föhrmann's escort agency, so the police team thinks of a client's jealous partner. Competing fitness center-managers Hassan Ahmed -barely breaking even- and -expanding- Lukas Hofinger were in contact with Weller, who booked his regular hotel three days for a poker night scam, and both lie about it. His admiring roommate, art student Tobias Küppers, sketches a robot picture of a man who threatened Weller. Next morning, Tanja Föhrmann is found murdered in the park.
