 After living in Shanghai for three years, Sarah (King), her husband, Jason (Chen), and their young son, Sammy (Oye), return to North America for a family funeral. But something strange is going on. Sammy starts seeing ghosts and then falls gravely ill. Traditional western medicine offers no hope. Sarah turns to a mysterious pharmacist who warns that her son is being held in a death grip by a living corpse. Sarah must find out what the spirits want if she is to save her child. Time is of the essence; once the sun rises the next day, the last day of Ghost Month, Sammy will be lost forever.
