In the late evening hours, after a demonic spirit invades her home and penetrates her mind, psychic medium Yvonne Saxon receives a series of horrific visions. These visions reveal the diabolical spirits' plans to exact their revenge on everyone who was in any way involved in the McLaughlin case just two months earlier. After several unsuccessful attempts to get through to and warn the family and her colleagues, Yvonne makes a last-ditch, desperate call to the Archdiocese in Boston --specifically, to Bishop Marcus Phelan, who had previously been so instrumental in that case. Bishop Phelan realizes the grave danger they face when he meets misfortune while setting out on the long drive to Connecticut. Will he reach the beleaguered family in time? Can he save his friends from the savage attacks Yvonne has revealed to him in her desperate plea for help?
