Ghost (1990)

Even though Sam Wheat, the successful investment counsellor, still finds it difficult to express his deeper feelings for her after all these years, his young potter girlfriend, Molly Jensen, is the love of his life. However, a curious case of a systematic discrepancy will prepare the ground for a hideous urban homicide in one of Manhattan's dark alleys, trapping, seemingly forever, the unfortunate deceased's immortal soul in the realm of the mortals. With the condemned spirit unable to interact with the physical world--and as Molly's life, too, is in grave danger--Sam will have to turn to the spiritual medium, Oda Mae Brown, to warn and protect her. Can Oda and the ghost settle the unfinished business in time?
