After receiving word of his grandfather's premature death, Chinook Shannon rides long and hard from Arizona to reach Bull Butte, Montana. When three local road agents fail to stop him from entering town, he arrives only to be told by the local banker that the family's Slash S cattle ranch--the largest in the territory--will be foreclosed in just twenty-four hours. Chinook soon discovers that it may be far tougher than he thought to discover who killed his grandfather and who is trying to take his ranch away, as he faces forgery, sabotage and murder!
