Who says the more the merrier?Is it possible for the human body to recover from supernatural possession?That's the question Josh Hewes and Crishtin Davenport grapple with daily as they attempt to rid themselves of two long-dead souls who have taken up semi-permanent residence in their hosts, using their corporeal bodies at whim to carry out their sexual pleasures. But when Josh jets off to Ireland for a paranormal investigation in one of the most haunted places in Europe, he soon discovers mixing spiritual possession with a malevolently haunted castle can carry grave consequences.
