The Seventh Day, the Eighth Night.

An allegory set in an archetypal Czech village, it tells the story of what happens when a series of mysterious events take place, including the disappearance of the station master. While everything has a rational explanation, collective paranoia takes over and everyone's worst instincts are unleashed. Interrogations, disenfranchisement, and the search for scapegoats ultimately lead to murder. The movie was completed in 1969, but it was banned and not released till 1990, Evald Schorm who died in 1988 never saw it completed.
