A beaten and incoherent man named Bain staggers into the drovers' camp. Trail boss Favor orders some of his men to search the surrounding area for the source of the trouble. Rowdy comes upon some hungry and mistreated women and a young boy alone on the prairie. He assists them by returning with food which one of them, Louise, repays by slipping a silver mirror into his saddle bag. Rowdy returns to camp where he and Favor along with Wishbone and Mushy go to a nearby settlement for supplies. At the store the owner recognizes the mirror as belonging to a woman killed by Comanches. He and others assume Rowdy is a Comanchero forcing the men to leave with no supplies. Meanwhile back at camp Favor starts putting the pieces together and finally learns from Bain that outlaws (Comancheros) are behind what has happened to the man, boy, and women and that the cattle herd is in danger. Rowdy leaves on his own to find the woman but is captured and tied up by the Comancheros. Louise releases and escapes with him. Bain leads Favor and the drovers to a sight where a battle ensues with the Comancheros over the young man - Bain's son. Bain admits he was to distract the men away from the herd. Favor and the drovers return in time to ambush the Comancheros as they attack the herd.
