Otets Sergiy

The life story of a young successful army officer, prince Kasatsky, who unknowingly falls in love with the mistress of the Czar. When he eventually finds out the truth about his soon-to-be-married wife (she wants to marry him to stop the rumors about her affair with the Czar), he is so shocked that he retreats to a monastery to become a monk (and after years Father Sergei). Later he battles with the temptations of sexual lust and the dreams of how things could have been. (IMDB comments)
