In 1874 Utah territory, young teamster Buck McCready becomes wagon boss for the Kavanagh freight outfit when his mentor, Mason Campbell, is murdered. With the Kavanagh outfit engaged in a freight wagon race that will decide who lands a lucrative hauling contract, Buck vows to find Campbell's killer. But first he must win the race-- with a saboteur on his crew, a hired gun out to take him down, and the possibility that Campbell's killer is after him, too.
