This rediscovered masterpiece captures a chilling moment in the stifling early days of Communist Czechoslovakia.

1950s Prague is a city of numerous daily terrors, of political tyranny, corruption and surveillance. There is no way of knowing whether one’s neighbor is spying for the government, or what one’s supposed friend will say under pressure to a State Security agent. A loyal Party member might be imprisoned or executed as quickly as a traitor; innocence means nothing for a person caught in a government trap. When a little boy is murdered at the cinema, the ensuing investigation sheds a little too much light on the personal lives of the cinema’s female ushers, each of whom is hiding a dark secret of her own.
