The Outsider
(2002) Rebecca (Naomi Watts) chooses Johnny Gault (Tim Daly) over her family and her Plain People way of life, and marries him.

Noah's son is shot by Mr. Hunter (John Noble), he loses his arm but it is implied that he lives, and the incident leads Johnny to have a showdown with Mr. Hunter and his men.

Johnny kills them all, but Rebecca is shot in the crossfire. Johnny throws away his guns and she recovers and they go back home to live happily ever after.

Thanks Naomi!
