An unstable gas station employee (Tracy Nelson) goes to extremes to thank the radio therapist (Shanna Reed) who helped her see the light -- and she starts by quitting her dead-end job, killing her disabled mother and stalking the doctor while working for her answering service. Before long, the grateful patient is holding the woman who helped her at gunpoint and demanding her undivided attention ... or else.
