A retailer is surprised when two boys buy the same playground equipment from him in quick succession, pay with small change and then always disappear immediately. He goes after them because he suspects something is wrong. So he comes to a car that is parked behind the neighboring casino with its tailgate open. In it he not only finds the small change lying openly in boxes, but also the apparently shot driver. Inspector Marie Brand and her colleague Jürgen Simmel appear at the scene of the crime to take over the case. The dead man is Sigmar Calser, the owner of the casino, who runs twelve casinos in Cologne alone and more in the surrounding towns. The two boys say they saw a hooded man at the car grabbing a bag from the back seat.
