Horst Fahrenbrink, a sleazy client of Alex’s, is found dead in his car after the two have met. Alex has since vanished without a trace. While Overbeck is firmly convinced Alex has killed her client and is on the run, Wilsberg and Ekki suspect she has been abducted and start to investigate.
Their only lead is a possibly valuable statuette of a redskin Indian, a gift from her client that Alex had in turn gifted to Wilsberg. And he for his part had flogged the figurine to a junk dealer for 20 euros. Barely have the two friends started their search than a second body falls at Ekki’s feet – from the window of multi-family apartment building.
By chance forensics find a woman’s shoe – belonging to Alex – in the apartment of the second victim. Overbeck sees his theory confirmed. But he has something else to worry about: for the Münster police masked ball he “borrowed” the police sedan of an officer from the State Criminal Police Office, which has unfortunately been stolen – of all people by Alex’s kidnapper.
While Overbeck is doing everything to trace the vehicle’s whereabouts, Inspector Springer attempts to solve the two murders. Wilsberg and Ekki look for the missing Alex, but without realizing that basically they are all pursuing the same objective. As it turns out, Alex is tied up in the trunk of the State Criminal Police Office limousine that has been abandoned in a deserted garage.
