In the 1870s, two rival businessmen, Zack Thomas and Joe Jarrett, on a stagecoach heading to Galveston, Texas, must pull together to protect $100,000 from an outlaw named Matson. Once in Galveston, however, their rivalry continues, as Thomas joins up with Elya Carlson and Jarret with Maxine Richter. But Matson is still on the loose, and a scheming banker threatens both Thomas and Jarrett.
