A bicycle courier who was delivering a painting has been attacked by a man using a bicycle and wearing the same uniform, the aggressor hit the bicycle courier who fell and later was hit by a car. The young biker called Daniel worked for a courier company managed by the former champion Utz Karger. His associate is Martin Jablonski. It seems that also other courier companies have been victim of attacks of the same type: a biker wearing the same uniform attacks the courier in a remote street. Ina searches in the company building and finds a doping pill (after analysis it's EPO). Besides the bicycle courier don't speak very much with the police. So Hajo accepts the proposal of Miguel to go undercover as bicycle courier in the company of Utz Karger.
