From Wikipedia: In the American West, a pioneer woman, Sarah, and six women, who are called her daughters, face frontier life. Rather than a straightforward storyline, the musical is presented as a series of short tales and tableaux matched with musical numbers, each presenting an aspect of frontier life or womanhood. The patches or blocks show "girlhood, marriage, childbirth, spinsterhood, twisters, fire, illness and death." The patches are ultimately put together to form one dramatic tableau.
