Acclaimed Czech filmmaker Jan Kadar adapted this depressing but effective drama from a best-selling novel by Lajos Zilahy. Yanos (Rade Markovic) is a married fisherman who falls in love with a beautiful and mysterious amnesiac woman, Anada (Paula Pritchett) whom he rescues from the water. The morally upright Yanos suppresses his lust for the woman, but becomes furiously jealous whenever she is approached by other men. His pent-up emotions consume him to the point where he ignores his sick wife (Milena Dravic), with tragic consequences. Kadar gets good performances from his talented cast, and the film is quite moving despite a year's delay in production resulting from the 1968 invasion of the country by Soviet troops.
