Do mediums spread false hope or provide much-needed comfort for the bereaved? This investigation follows four mediums who claim to receive messages from beyond the grave. Dubbed "The Psychic Barber", Gordon Smith's unnerving accuracy has silenced even the most hardened of cynics. Can he get to the bottom of some ghostly goings-on? Meanwhile, husband-and-wife team Jane and Craig Hamilton-Parker help a group of student psychics to tune into the other side, while blind medium Sharon Neill embarks on a sell-out UK tour.
