Older cowhand Slim Jessup (James Gregory) is accussed of killing a man in Idaho and escapes east. He signs on with a Shiloh Ranch cattle drive to Moose Jaw, Saskatchewan. On the way the drovers are joined by a young man, James Cafferty (Bandon de Wilde), who wishes a different life than dirt farming with his widowed step-father (Frank Overton). The older Slim takes James under his wing and teaches him lessons in life before his past catches up with him.

Trampas and Betsy Garth discover the body of a murdered neighbour, Mr. Keel. Trampas encounters a Latvian immigrant, Karl Rilke (Karl Boehm) and his pregnant wife Maria (Ilze Taurins), and discovers they have Keel's rifle although Karl claims he bought the gun from a man on the road. Judge Garth believes Karl innocent and that Keel's son Johnny (Robert Duvall) is the murderer, so he defends Karl at the trial.
