An Angel's Trail

S4 E21: Jill Munroe is taken hostage when she accidentally stumbles into a gas station robbery. Convict Sam Mason and his sons, Clint and Harley, escape into the desolate desert hills keeping Jill tied in the back of their getaway van. Tiffany researches the geography of the highlands and discovers an old road overlooked by the search party. Hampered by wind and rain, Kris continues to lead the search for her sister when they find indications that the convicts are nearby. Jill befriends the retarded Harley who retaliates against his cruel father by battering Sam unconscious -- saving Jill from certain death. Jill sees that Harley receives special attention in the best institution for the mentally handicapped.
