The Shadow Riders

At the end of the Civil War, Confederate soldier Dal Traven (Sam Elliott) is about to be executed by a firing squad when he is rescued by a cavalry force led by Major Ashbury. Ashbury plans on continuing to fight the Union and invites Dal to join his group. Dal declines, deciding to go back to his home in Texas instead. On his way there he meets his brother Mac (Tom Selleck) who served as a Union officer. Despite serving on different sides the brothers bear no ill will toward each other.
