Two young Navajos hitch hike home through the Navajo reservation, falling in love along the way.

In 1934 on the serene Navajo reservation, Mary Jane spends her time daydreaming and tending to her family's flock of sheep. When her older sister returns from boarding school with a world geography book, she reveals new worlds that are "just over the mountain." Conflicted by her obedient nature and her curious imagination, Mary Jane must privately decide to either maintain her lifestyle or depart into the exotic unknown.
