Suppressed shortly after it was made but reappearing in 1991 at the Cannes film festival, this 1970 Czech feature by Karel Kachyna, coauthored by the late Jan Prochazka, is a “paranoid” suspense film about a high-level government official (Radoslav Brzobohaty) and his wife (Jirina Bohdalova) who discover their house is bugged and that he faces imminent arrest.
