While on a tour in Hollywood, a young couple, Joel and Donna Gregory (Robert Wagner and Kate Jackson), arrive at the house of Lorna Love, an infamous actress who died in 1935. There, they meet with housekeeper Clara Josephs (Sylvia Sidney) and agent Oscar Payne (Bill Macy), to investigate the mystery behind Lorna and finish a book that they are writing on the actress, an interest that came out of the discovery that Joel's father was her lover. While staying at the mansion, strange incidents occur. The couple immediately notice a portrait of Lorna, painted by Joel's father, and shortly after, Donna catches a 1930s-dressed woman at the center-located shrine in the garden.
