As proprietors of the growing D&T Cattle Company, veteran cowboys Casey Tubbs and Eli Doolin finally have a business of their own. Unfortunately, the cattle market has seen better days and the D&T's finances are drying up -- leaving Casey and Eli no choice but to procure cash by any means necessary. Before long, the two bank robbers are the most wanted men in the west. Dogged by U.S. Marshals and Texas Rangers, the old cowboys slip away time after time, gaining notoriety and being hailed as heroes by folks who have been victimized by corrupt bankers. Deputy U.S. Marshal Colton Gray respects Casey and Eli's grit, but won't let that stop him from bringing them to justice.
