This 1974 horror film tells about a young woman, Amanda Post (Susan Bracken) who returns to her childhood home 13 years after her mother's murder to tend to her ill grandmother. Soon, she gets phone calls from the killer who is obsessed with her. This isn't a bad flick that obviously inspired "Scream" & "When A Stranger Calls" with some suspenseful and somewhat disturbing moments, a sexy female lead and a decent score. If you're into psychological horror or thrillers, you might want to give this a try.
