EastEnders actor Joe Swash turns ghostbuster and sets out in search of tangible proof that ghosts exist. He meets Britain's youngest professional psychic, who claims he has a hotline to the spirit world, sleeps in a haunted bedroom to lure an amorous spirit and stakes out a terrace house in Hartlepool where the family say they're sharing their home with at least four ghostly inhabitants. But it's a night alone in the Edinburgh vaults that makes Joe convinced he really believes in ghosts.
