Zinat runs a health clinic in a remote part of Southern Iran where she dispenses advice, medicine and baby formula. Although it is unusual in her conservative village for a young, unmarried woman to have such a position, Zinat's expertise and hard work make her invaluable to the community.

When Zinat becomes engaged to Hamed, his disagreeable mother demands that she quit her job. Zinat tries to be a satisfied wife and daughter-in-law, but when a medical emergency develops in the village, she is forced to choose between her duty to her family and her commitment as a health care provider.
