A cash truck is robbed on the highway, and while Semir and Tom are chasing the gangsters, Engelhardt is seriously injured in an accident. She has to go to the hospital, and surprisingly Herzberger is appointed as her replacement. Semir and Tom discover that only certain paintings by an artist were stolen, which were intended for a planned exhibition in the museum. The gangsters demand a ransom, but while the police try to monitor the handover, the criminals rob the art shipment again. Tom is dragged out of the truck and briefly sees the leader's face.
