On the trail to New Mexico, Pat Stevens and his friends Sam and Ezra risk their lives to fulfill a dying man's last wish. Two men ride across the desert. One is young, nearly mad with thirst and fear. The other is stalwart - a blue-eyed legend who doesn't panic at the sight of a hanging posse on their trail. He asks no questions of the young man whose life he's agreed to save. He simply rides. It has been fifteen years since a youthful Pat Stevens, wrongfully accused of stealing horses, placed his life in the hands of the legendary Mose Higgins. Since then, Pat has settled in Powder Valley and hung up his guns to run his ranch and raise his family. One day, a strange letter comes from New Mexico. Someone has threatened Mose's life, and only Pat can rescue him and his innocent little girl. Pat owes Mose a priceless debt - and it can only be paid in blood.
