Cowboy Steve Kinnard (Steve Carrie) travels from the Texas badlands down to Argentina and finds even more adventure. The invalid Don Esteban Valdeo (George Gyton) owes Don Pedro Martinez (Merrill McCormick) a large sum of money. Martinez insists that either he gets the money, or the hand of Valdeo's daughter Felicia (Marin Sais) in marriage. Felicia convinces her father to send her mother's jewels as payment. Martinez kills the man who brings them, and places the blame on the recently-arrived Kinnard. Kinnard discovers the identity of the real killer, but has to be rescued by Felicia and a group of ranchmen from Martinez's vengeance. ~ Janiss Garza, Rovi
