Sheep ranching is an Idaho tradition that dates back to the 1880s. Frank Shirts is one of Idaho's largest sheep ranchers. He runs 12 bands, or about 28,000 ewes and lambs, from the low country in Wilder near the Snake River to the high country in the Boise and Payette National Forests every year.

The Life on the Range crew followed Shirts' sheep flocks for a year, tracing the process of raising sheep from when the lambs are born, to spring turnout, range readiness, summer grazing, shipping to market, and shearing.
