Peter Rader directed this horror film about a teen-aged orphan named Lynn (Kim Valentine) who accompanies her young brother David (Eric Foster) to live on their grandparents farm after their father dies. Before long, it becomes obvious that all is not right on the farm, and that the grandparents (Ida Lee and Len Lesser) are hiding a dark secret. Cult favorite Brinke Stevens stars as the kids insane mother, whom the grandparents have drugged to control her homicidal impulses, and screenwriter Peter Jensen provides the atmospheric photography. Some chilling moments and a particularly creepy performance by Lesser make this average slasher film worthwhile. Producer Nico Mastorakis had co-written the story for the abominable The Greek Tycoon (1978) before turning to genre filmmaking. ~ Robert Firsching, All Movie Guide
