Frightmare

Two decades ago, Edmund (Rupert Davies) and Dorothy Yates (Sheila Keith) were placed in an insane asylum after it was proven they were cannibals who'd killed and eaten six people. Now they've been set free, and their put-upon daughter, Jackie (Deborah Fairfax), is beginning to suspect that they may not have been entirely reformed. As various young people start to disappear from the area around her parents' cabin, she and her boyfriend (Paul Greenwood) begin looking for evidence.
