Castle Rock

Andy’s mother has had enough of her rebellious teenage daughter, so she sends her out into the desert near Castle Rock with her Grandpa (Ernest Borgnine) and his dog, Farley, for a serious reality check.
As they’re setting up camp, Farley takes off and Andy goes looking for him. When she returns her grandpa is nowhere to be found - rescued by some locals after suffering a terrible stroke.

Now Andy and Farley are alone in the desert with no other options except to make the trek to the nearest town. But they’re not alone for long when they come across Antonio, a young illegal immigrant on the run from the border patrol.
