After Sandy Burke rescues orphaned seven-year-old Dolly Morgan from Jim Diggs, who gunned down her father, he gives her to the Widow Mackey to rear. Learning that the widow's mortgage soon is due to Digg's partner, Lafe Hinton, Sandy goes to rancher Jeff Kirby for a job, but is mistaken for desperado Slim Dillon, and captured by Kirby's daughter Molly. After Sandy proves his innocence, he masquerades as Dillon and robs a stagecoach to help the widow. Sandy wins the mortgage money playing poker with Hinton. Kirby hires Sandy to stop the thieves rustling his prize steers. Sandy suspects Diggs and Hinton, and after he rescues Molly from Diggs, he finds a letter from a packing firm which proves his suspicions. Diggs recaptures Molly, and Sandy, pursuing, falls into Diggs' trap. As Diggs prepares to brand Sandy's bare back, Molly's pleas give Sandy the opportunity to pry loose. After capturing Diggs, Sandy, who loves Molly but thinks that she loves another, says goodbye. Molly then takes his revolvers and orders him to put his hands up and around her.
