Somewhere on the periphery between Frankfurt and Offenbach there is an old, lonely police station. It is now a police museum, will soon be closed and only houses two police officers: Walter Brenner (Peter Kurth) and his colleague Cynthia (Christina Große). Brenner is an old friend of Felix Murot (Ulrich Tukur). He decides to visit his ex-colleague from the BKA days. In the meantime, something is brewing in the city: a solar eclipse, a daughter who has avenged her murdered father and escapes to the infirmary, and a prisoner transport with serious criminals who ends up stranded in front of the infirmary with a flat tire. Suddenly the station is fired upon, a gang opens fire - all hell breaks loose...
