Gregory Peck stars as Sam Varner, an ex-Army man who escorts a girl (Eva Marie Saint) kidnapped by Apaches across the desolate Southwest. Joining them are the girl's half-Indian son and Varner's best friend (Robert Forster). But their long journey across the desert won't be alone. Following close behind is a a man intent on stopping them--the boy's homicidal father. It's a game of cat and mouse in this Western thriller that reteams Peck with TO KILL A MOCKINGBIRD director Robert Mulligan and producer Alan J. Pakula.
