Pursued

Raised by a foster family, Jeb (Robert Mitchum) is an orphan who remains tormented by the traumatic murder of his parents when he was a child. He is treated well by his foster mother, Mrs. Callum (Judith Anderson), and her daughter, Thor (Teresa Wright), but he and foster brother Adam (John Rodney) have a tense relationship. When Jeb is shot at while riding his horse, he blames Adam -- but Mrs. Callum knows that in fact it's another member of the Callum clan who is out to get him.
