*Clumsy youngsters Lukas Feldmann and Marvin Berg make a failed attempt to rob Wilsberg's antiquary library, during which Ekki manages to knock down shy Marv. When Lukas is found murdered by pushing down a bridge, Overbeck insists to haunt Wilsberg, who tracked them down, as prime suspect, who prefers to run and conduct his own parallel investigation. The knaves' lonely senior neighbor, in a wheelchair, is found dead for weeks in his apartment. Ekki takes risks to investigate suspicious irregularities in the books of investment firm manager Horst Große-Eschhaus, whose money-laundering turns out to link with both murders.
