Bulcsú (Sándor Csányi) is a subway enforcement officer working in the oppressively gray underground transit system in Hungary, whose job consists of ensuring commuters have paid to ride the train. A quirky young woman (Eszter Balla) catches his eye, and their relationship suggests that Bulcsú might escape from the drudgery of his subterranean life and finally see sunlight again. But first he needs to find out why passengers are jumping -- or being pushed -- to their deaths onto the tracks.
