Chad and Joe set Ranger Jess Moran up for a 4th of July boxing match with Calvary champion Percy Flower, the bet being a month's pay. The Pryor Gang is in the territory and Captain Parmalee is worried about them hitting the next silver mine shipment so he cancels the holiday for the rangers and assigns six of them to be on duty in town while he waits at the mine with the rest of the rangers. Chad, Joe and Jess are three of the six left in town. The Captain has agreed that one of them may leave guarding the silver bars if all of them agree it's necessary. Their problem will be getting straight-laced Ranger Gruber out of the way. Insurance man Wilson Jones helps them do this. Once Chad, Joe and Jess leave for the boxing match the Pryor Gang strikes and steals the silver. Jess twists his ankle just before the fight and Joe has to face Flower. Chad and Joe leave to chase the Pryors and capture them and recover the silver while Jess takes a swing at Flower and knocks him out.
