A man was killed in a secret location under a bridge. The chief inspectors Ballauf and Schenk find out that the victim, the unemployed Peer Schwarz, was deliberately run over by a car. In his apartment they find large amounts of cash and documents that point to the systematic blackmail of well-known personalities.

When Ballauf realizes that there could be a possible connection between his private happiness and the current case, his newfound work-love balance becomes a tightrope walk for him...
