If the perpetrator is in firm denial and there is no evidence, there is nothing left but to set a trap for him. When it is necessary to convict a bomber in custody, Commissioner Brandtner poses as the arrestee and helps the person to escape during the transfer to another prison – but the person does not trust him very much. Other policemen – Böck and Hellerer – secretly join the action, but the dangerous criminal works principally as a soloist and soon gets rid of the unwanted guides. Will the criminalists catch him before he starts blowing up objects full of innocent people again?
