Annie and Charlie Darke suspect someone is trying to chase them from their Wyoming valley home. Wes Gray, a friend of Annies's Uncle, travels to Beecher's Gulch to investigate and arrives just in time to rescue Charlie from a lynch mob.

Then he's catapulted into a violent struggle to save the Darkes' ranch when the son of their neighbour, Duke Barton, is ambushed and Charlie becomes the main suspect. Wes is determined to discover the truth, but the more he learns the less sure he is of the true motive of the Darkes' enemies.

Up against a sheriff who may be on Duke Barton's payroll and the Cheyenne Indian, Hawk, has Wes met his match?
