In 2019, Union Berlin was promoted to the Bundesliga. Four years later, the traditional East German club qualifies for the Champions League and achieves something that few would have thought possible. Despite all the euphoria over the triumph, the pressure to remain strong in sporting and economic terms also increased, as did the fear of falling into a conflict of identity between tradition and change. The fact that the soccer underdog from Köpenick still manages to retain its magic is primarily down to the people who work behind the scenes to keep things running smoothly and enthusiastically. Always at their side: a loyal fan base that is prepared to follow their club's path unconditionally. Hendel follows the team behind Union for almost two years, right up to their entry into the top flight, and takes a unique, particularly personal and authentic look behind the scenes of the club.
