Abigail tells the story about a young couple, Miriam Natias and Jonathan La'Fey, who move into an old mansion that La'Fey inherited. It takes place in the summer of 1845. At their arrival they are warned by seven horsemen not to move into the house because if they do "18 will become 9." They do not heed the warning and proceed to move into the mansion. During their first night, Jonathan meets with Count La'Fey, the Family Ghost, who is a deceased relative. The ghost shows him a casket in which a corpse of a stillborn child, Abigail, rests. The ghost informs him that Miriam is carrying the spirit of Abigail and that the child will soon be reborn. He asks Jonathan to kill his wife to prevent the rebirth. In the meantime, the story unfolds of what happened to the Count and his wife; she gave birth to Abigail on 7 July 1777. The Count had thrown her down the stairs, causing her neck to break as well as the death of Abigail, who was an illegitimate daughter. The next day, Miriam is clearly pregnant and the fetus develops quickly. Jonathan contemplates throwing her down the stairs, encouraged seemingly by his wife. However, Miriam throws him down the stairs and gives birth to Abigail. But Miriam does not survive the birth, and Abigail is left alone. At that moment the seven horsemen arrive again, planning to destroy Abigail once more.
