It's been eight years since Sam Holt brought his family to Paradise Valley and began the Rainbow Ranch. Along with his wife Helen, son Bruce, and daughter Mary, Sam brought Morgan Drew, the orphaned son of a friend. Since then, Morgan has created his own ranch, the area's second largest. Romances, rivalries and feuds have taken their toll. But now the Paiutes have declared war on all the ranchers, and that will change everything.
