Desolation Canyon

After a bank robbery, the responsible gang stops by the home of one of their band's estranged wife to abduct his own young son. The town's old sheriff (Patrick Duffy) calls for the help of a retired gunfighter (Stacy Keach), who is also the abducted boy's grandfather. Hot on the trail of the fugitives, they discover that two bounty hunters are already in pursuit of the gang for crimes committed in Mexico.
