Waking up one day in his own bed, Jurek Kiler is arrested by an anti-terrorist brigade. The police take him for a dangerous criminal, as a rifle was found in the boot of his taxi, with which a man had been killed the previous day. Jurek is sent to prison, where he immediately becomes a star among criminals. It is no use explaining that the accused is just a taxi driver. Superintendent Ryba cannot be persuaded; he is absolutely certain that he has caught a serial killer wanted all over Europe. Upon hearing of Kiler's arrest, Siara, a big shot in the criminal world, organises a swift operation and recaptures him from the police. Not knowing who he is really dealing with, he assigns him another task. Rumours of Kiler's incredible exploits spread ever wider. Jurek, meanwhile, comes to the conclusion that explaining the misunderstanding is not worth it at all. With the help of a journalist, he hatches a cunning plan.
