S56·E1 The stilt man

Paul is kidnapped in the street. An attentive neighbor is killed by the kidnapper before she can give a statement. The parents receive a ransom demand, but detectives Lena Odenthal and Johanna Stern determine that it is a diversionary tactic. The case is strikingly similar to a kidnapping nine years ago, in which Swen, who was nine years old at the time, was released after months of captivity, apparently unscathed, but the perpetrator has not yet been identified. Swen seems to have survived the terrible experiences of his childhood. But he still cannot help the detectives, even though Johanna Stern manages to build a good relationship with the unstable young man. The detectives realize that Swen is being haunted by ghosts from his childhood experiences and that he is still traumatized. They need his memory to find the way to the kidnapper.
