The Good Wife (1987)

The isolated Australian outback in 1939 provides the setting for this drama about a lonely, discontent housewife. Marge Hills lives a quiet, unexciting life with her dull-witted, unaware husband. Then a new man comes into town, and he gives Marge one chance -- and only one chance -- to accept his propositions. Marge refuses, but gradually becomes consumed with desire for him. Though it seems opportunity has passed her by, her desperation grows and leads her to become incautious... threatening her marriage, her reputation, and the stability of her existence.
