North of the Rio Grande

Son of Colonel Haddington, Bob leads a posse against raiders in a settlement. During his absence, one of the prize horses is stolen and his father is killed. Bob swears revenge and becomes known as Velantrie, leader of a band of semi-outlaws, and befriends a priest, Father Hillaire. At a mission, he meets Val, daughter of John Hannon, a wealthy ranch-owner. Later, Bob is suspected of being the feared "Black Rustler," but he learns that Hannon is indeed the guilty party and the man who killed his father. Bob decides to leave; but he meets Hannon, who has been wounded, and exchanges places with him. Hannon confesses to Val and dies in her arms; she rides to rescue Bob just as he is about to be hanged.
