Vienna, during Easter time. After a billiards tournament at the café "Heller," the winner, Georg Fellner, is pushed in front of a car. No one saw anything clearly, as it is night and pitch dark due to a power outage. The first suspicion falls on his opponent, Egon Sykora, who left the café after Fellner's unsportsmanlike behavior amid wild threats. However, there are a whole host of other suspects, as Fellner was a cynic and provocateur whom hardly anyone could stand. Alongside Chief Inspector Juricek, Chief Officer Leopold and his friend Korber set out to find the perpetrator. While Korber inquires at the billiards club Alt-Floridsdorf, Leopold follows the trail of a movie ticket he found next to the body.
