Angie (Salley Yeh), a Ph.D. student working on a thesis about Chinese superstition, is thrilled when she moves into a gorgeous --and cheap -- apartment. But it turns out there are a couple of residents she didn't know about … ghosts! When the apparitions' escapades lead to crime, a policeman (Chow Yun-Fat) offers Angie help with a much-needed exorcism -- and a little personal protection.
