Meanwhile, the USA President s godson Robert Thorn is informed in the maternity in Rome by Father Spiletto that his wife Katherine has just lost her baby and she had troubles with her uterus and would not have another pregnancy. Spiletto suggests Robert that another just born child that lost his mother could be the substituted for his son, and Robert accepts the child and gives the name of Damien. Robert is promoted to ambassador in London after a tragic accident. When Damien s nanny commits suicide in his birthday party, a substitute, Mrs. Baylock, comes to work and live with the family.

Robert and Katherine Thorn seem to have it all. He is the US Ambassador to Italy and they want for nothing in their lives, except one thing: they do not have children. When Katharine has a stillborn child, Robert is approached by a priest at the hospital who suggest that he take a healthy newborn whose mother has just died in childbirth. Without telling his wife he agrees to to so but after relocating to London, strange events and the ominous warnings of a priest lead him to believe that the child he took from that Italian hospital is evil incarnate.

Damien Thorn is dead, but his prophecy is reborn in a mysterious girl named Delia, who is adopted by two attorneys, Gene & Karen York. When Karen realizes her baby was born under suspicious circumstances, she hires a private investigator to find Delias real parents. A series of bizarre accidents occur, and Karen begins to suspect everyone of conspiring against her as she unravels the truth about her baby.
