Pamela Ryan's marriage is over, but her emotionally disturbed husband, Norman, tells her he'd rather kill her than to let her go. The stress of her disastrous marriage finally catches up with her in a mysterious way. In a Scottish tearoom, she finds herself lapsing into a Scottish dialect. Suspecting her strange behavior is in some way related to reincarnation, she, without telling Norman, seeks the help of past-life regression therapist Dr. Martin Bradford.
Under hypnosis, Pamela discovers she was Sarah MacAllister, a young Scottish girl engaged to Robyn Macqueen. As session after session reveals the details of Pamela's past life-of her death and her grief-stricken fiancé's suicide, she and Dr. Bradford grow closer. But Pamela doesn't fully understand the pull of her attraction towards her therapist until she discovers that Dr. Martin Bradford was none other than Robyn Macqueen.
In spite of Norman's murderous threats, the reunited lovers make plans to flee the country and to look for their past-life parents. But when Norman discovers their plans, he vows to find and kill them.
