Hammer Films' Nightmare walks the thin line between sanity and madness, exploring the shadowy world between dreams and reality. As a child, Janet (Jennie Linden) witnessed her insane mother stabbing her father to death. Now a young woman, Janet's recurring nightmares have her convinced she'll follow her mother to the asylum. Accompanied by her schoolteacher Miss Lewis (Brenda Bruce), Janet retreats to the home of her guardian (David Knight), who has hired lovely Grace (Moira Redmond) as a companion to help calm his troubled ward. But Janet's nightly terrors, magnified by the eerie, creaky old house, bring all of her fears chillingly to life. Startling twists and turns reveal that sometimes when you wake up, the nightmare is just beginning. © 1964 Universal Studios. All Rights Reserved.
