For train manager Anja Szeglat, her ICE train journey from Hamburg-Altona to Frankfurt am Main begins with a delay: her train has no power. The night shift begins at the ICE workshop in Hanover. Markus Dolle and his team are under time pressure. In just three hours, an ICE train is scheduled to depart for Stuttgart. But a door is broken. Federal police officers also have to act quickly. They are searching for a passenger who has fled Hanover Central Station without a ticket. And near Bad Münder, vegetation experts have to fell a tree right next to the tracks.
