As the patriarch of a large and growing family that resides in the
Grand Teton Mountains in Wyoming during the early 1960s, dirt-poor
sawmill worker Clay Spencer is fiercely independent yet dedicated to his family. He navigates issues of religion and education to eke out a brighter future for his offspring. Clay Sr. is the oldest of eight boisterous brothers, all of whom live within visiting distance (and apparently all single). Clay's elderly parents also live nearby on the mountain, named "Spencer's Mountain", after their pioneer family. Hardworking wife Olivia is loving and faithful, kept busy with household tasks and contending with her husband's rough-hewn ways, which include periodic drinking sprees in town and a vocal refusal to attend his wife's local church services. Eldest son "Clay-Boy" aspires to attend college and build a career away from the mountain. To do so, he must earn a scholarship and be approved and admitted by university officials. He fears that his unpolished family, particularly father Clay Sr., may hinder his pursuits. Clay-Boy must also contend with the amorous pursuits of teenage neighbor Clarissa, daughter of the wealthy local mill owner Col. Coleman, who employs Clay Sr. and acts as de facto power figure of the mountain community. Clarissa's amorous campaign with the Spencer boy includes several brazen attempts to seduce Clay-Boy, brazen enough for folks who observe several incidents to draw comparisons to barnyard animals in heat. Meanwhile, since his marriage to Olivia, Clay Sr. has dreamed of building a spacious house farther up on the mountaintop for the two in which to retire. Periodically, he breaks away from work to continue the long building process on this house, using building materials that he has been able to assemble with great effort and sacrifice. However, after ten or more years, the mountaintop house remains mostly an unfinished frame. Eventually, Clay-Boy wards off the attentions of Clarissa, and completes an independent-study tutoring course in ancient
Latin (required for his particular type of scholarship). His admission to the state university is approved, but Clay Sr. realizes that the family cannot afford both his longtime dream house and sending his son to college. As a result, he decides to sell the mountain house property to direct the profits to Clay-Boy's college expenses, and sadly torches the unfinished structure of lumber framing. Olivia is shocked by Clay's actions and assumes that he must be delirious with grief at the loss of the house. He responds with a laugh, telling her that the house had indeed been his dream, but insignificant when compared to the chance of sending their son to college. In the end, Clay-Boy is admitted to college and bids farewell to his family. ==Cast==
