George & Margaret Blackledge (played by Kevin Costner and Diane Lane), are a retired sheriff and his wife living with their son, daughter-in-law and grandson, on a Montana ranch. Their son, James dies in a horse riding accident and then many years later, their daughter-in-law, Lorna , remarries Donnie Weboy. Margaret sees that this union is very abusive and wants to get her ex daughter-in-law and grandson back. Lorna, Donnie and her son are taken away by Donnie's family. And George and Margaret must go to long measures to locate their grandson. Neither Donnie's family or George & Margaret are willing to let the boy go and George must rescue his grandson before it's too late. Very good movie.
