The Girl on a Swing, a haunting, mystery thriller with a supernatural twist, is the story of a desperate woman, who will do anything to be with the man she loves. Karin Foster (Meg Tilly), a lonely German secretary, falls in love with and marries Alan (Rupert Frazier) and moves with him to England. There her strange behavior and fears strain the marriage and lead Alan to mistrust his wife and begin to delve into her past. Based on the novel by Richard Adams, the film is not entirely successful due to the leisurely direction of Gordon Hessler and the lack of pace needed to create genuine suspense. But despite this flaw, the sensitive performance of Meg Tilly makes the film well worth watching and is a haunting psychological exploration of obsession, passion and guilt.
