Kit and El Toro attempt to rescue a man being dragged behind a horse but are too late to save his life. Knowing that the man was the foreman for his old friend, Ray Bolton, Kit visits the ranch and meets a stranger who declares himself to be its new owner. Kit manages to sneak inside the ranch house and rescues Ray, who is bound and gagged in the basement. Kit learns that Ray's lovely daughter has been abducted to force him to sell the ranch to crooks.
After finding a friend and fellow lawman murdered for some gold, Carson and El Toro go to a small Mexican border town to await the arrival of the gang. Toro is mistaken for a bullfighter of some fame, and gets mixed up with the innkeeper's daughter and desperately tries to get out of an impending shotgun wedding.
When El Toro receives a desperate plea from his uncle, Manuel Lopez to come to his aid when a family feud is rekindled, Kit Carson volunteers to join the fight. The argument started over the possession of an inheritance of family jewels that the Hernandez clan claims is rightfully theirs. Kit discovers that the Hernandez clan has resorted to forgery, murder and buying off a judge to make their claim stick.
