Ralph Kincaid, a wealthy rancher, catches his son, Juro, stealing money from his desk so he can pay his gambling debts and brutally beats him. The next day, the father is found murdered and the evidence seems to point to his son as the killer. During the trial, Captain Rynning discovers incontrovertible that the young man was incarcerated in another town at the time of the murder after suffering from a blackout. The ranger thinks the explanation is too pat, though, and searches for Juro's murderous accomplice.
