The Occupant (1984)

Angie (Sally Yeh), a college student from Canada, returns to her native Hong Kong to work on a Master's thesis focusing on the superstition. Her topic will get much-needed attention as the spacious apartment rented out to her by women-crazed real estate broker Hansom Wong (Raymond Wong) is haunted by the ghost of a singer, whose life was cut short due to a triangle relationship argument. The ghost appears thereafter and, joined by cop Valentino Chow (Yun-Fat Chow), the three attempt to appease the spirit and send her back to the afterlife.
