Reich oder tot

Diller and Kessel, two hardened Hamburg investigators, learn that their "old buddy" Mohammed is planning to rob a bank with his buddies. Kessel is a customer there, of all places. Kessel is divorced because of previous drug problems, but has resolved to win Claire and the children back and has therefore been clean for months. Despite Kessel's warning to the branch manager, the gangsters carry out their plan and take a hostage who happens to be there: Kessel's daughter Ruby, who suffers from epilepsy.
