During a routine questioning of Steier (Joachim Król) a catastrophe occurs. A little girl is fatally injured by a ricochet. However, the perpetrator was acquitted in court because the lawyer questioned the statement made by Inspector Steier, who had drunk a lot in a pub the night before the operation. Steier is beside himself and resigns from the service, wanting to "finally be a hero in his own film again". He loads his pistol and pursues Nico (Maik Rogge), who fired the fatal shots. He comes to his senses at the last moment, but finds out that Nico is planning a burglary together with his brother Robin (Vincent Krüger) and his junkie girlfriend Lisa (Janina Schauer). It ends in disaster, the homeowner who has returned unexpectedly is killed.
A neighbor, Rolf Poller (Armin Rohde), has observed everything and gets caught in the crosshairs of the trio of burglars who want to get rid of the witness. While trying to save Poller, Steier is knocked down by the latter in his house and locked in the basement with Nico and his brother's girlfriend. He locks Robin in his son's former youth room. Poller follows a perfidious plan. He too finally wants to be the hero in his own film again. Only his version follows a completely different script.
