Rigor Mortis is set in a creepy and moody Hong Kong public housing tower whose occupants, we soon discover, run the gamut from the living to the dead to the undead, along with ghosts, vampires, and zombies.
Rigor Mortis stars action movie veteran Chin Siu-ho (Siu-ho) as a former vampire hunting actor who now finds himself reaching the end of the line as a washed-up star, separated from his wife and alienated from his son. Down on his luck and with barely a dollar to his name, he checks into Room 2442 in the housing estate, an allegedly haunted flat. His aim is to end his misery by doing himself in, but instead Siu-ho is interrupted by some of the other “occupants” of the building including a Taoist master-exorcist (Anthony Chan), a traumatized housewife with a tragic past (Kara Hui), as well as a seemingly benign elderly woman (Paw Hee-ching) who has an empty coffin conspicuously hanging in the middle of her apartment. Soon it becomes apparent to Siu-ho that the people around him and the situation are far from normal. Despite his lack of belief in superstition, Siu-ho is soon thrust into the battle of his life as vicious vampires with unsettled business begin to rise from the dead…”
