They Wait

Overview:

Jason and his wife, Sarah, leave their adopted home of Shanghai and travel to Vancouver, British Columbia, for his uncle's funeral, staying with his Aunt Mei. Already disoriented, Jason and Sarah are unnerved when their son, Sam, begins seeing ghosts and violent deaths. After Sam is hospitalized, Sarah consults with a pharmacist who's well-informed about Chinese mythology and who tells her that supernatural forces threaten her son.
