At the station of Almamellék the semaphore turns red unexpectedly and the conductor shows a stowaway - with no money nor ticket - off the train. The stowaway has to undergo a serious and long investigation that tries to uncover the reasons for his "deed". In the meantime he can watch, like a spectator in a movie-theatre, how Kerek József, the strutting stationmaster rules his ridiculous empire through office bureaucracy, indifference, servility and negligence.
