Released after ten years in prison for kidnapping an entrepreneur's wife, ruining him for the million Euro ransom, which was never found, Carla Funke surprises senior detective Martina Seiffert in her garage, having bitterly sworn revenge on her at the trial. However she now only besieges informal help to solve the kidnapping of her own son Alex Funke, a bright student who was raised by foster mother Susanne Seidle, who claims Alex refused any contact with his con mother or to attend her release. The never found million is demanded in a video from the kidnapper. Prime suspect is Jürgen Sessler, who was ruined by paying it for the release of his wife Carla Funke, who left him and recently committed suicide. The team identified Carla's then accomplice, who may be after a share of the fortune or besotted with Carla, who may have staged everything to 'launder ' the cash. Sessler hired as amateur private detective student Hanna Schütz, who seduced Alex Funke. Then Carla Funke goes missing, but Rico guesses smartly.
