Taking place over the course of a single psychedelic Halloween night in a ghostly Blackpool, depressed Greg Kielty's life is turned upside down when his estranged brother Dan turns up, claiming to have drunkenly run someone over. But has Dan in fact just murdered a psychopathic gangster's son? Or maybe he's stage-managed the whole scenario to scare Greg out of town so he can cement his affair with Greg's wife?
