In rural Republic of China (1912-1949), in 1935, all but one of the white residents of a remote Christian mission post are women. The strict Miss Agatha Andrews (Margaret Leighton) is the head of the mission, assisted by the meek Miss Argent (Mildred Dunnock). Charles Pether (Eddie Albert) is a mission teacher who always wanted to be a pastor; his peevish, panicky, self-centred and domineering middle-aged wife Florrie (Betty Field) is pregnant for the first time. Emma Clark (Sue Lyon) is the only young staff member, whom Miss Andrews treats as if she was her daughter.
