CHILDREN OF THE CORN 666: ISAAC'S RETURN

Hannah, born in the original Gatlin, Nebraska cult led by nefarious prophet Isaac, visits the town to find her birth mother. After having a mysterious encounter with a street preacher, Zachariah, Hannah crashes her car in a cornfield. She is escorted to the hospital by the sheriff, Cora, where she is examined by Dr. Michaels. There, Hannah finds that Isaac—long thought dead—has been hospitalized in a coma for years.

After she leaves the hospital and resumes her journey, she is nearly driven off the road by a mysterious truck. After checking into a motel, she meets a pair of romantically involved teenagers in the motel office, the standoffish Morgan and her boyfriend, Matt. The following day, as Hannah leaves, a small crowd gathers around her car, fascinated by her. Meanwhile, Isaac awakens from his coma and learns he has a son. Hannah returns to the hospital and encounters Gabriel, who helps her find her birth certificate. She is attacked by Jake, who attempts to kill her with an axe, but he is stopped by Gabriel.

Hannah experiences a number of strange visions, and learns that the woman who attempted to force her off the road was Rachel Colby, Hannah's birthmother. At the town church, Rachel confronts Isaac, who accuses her of betrayal. Dr. Michaels acts as a confidant to Rachel, urging her to stop Isaac. Shortly after, Isaac kills Dr. Michaels before approaching Matt, revealed to be his son who he hopes will carry on his legacy. Meanwhile, Rachel confronts Hannah, whom she long believed to be dead, but is evasive regarding the events surrounding Hannah's birth, only commenting that it has been prophesied that Hannah would return to Gatlin on the eve of her nineteenth birthday.

That night, the cult gathers in the cornfield under Isaac's command, branding Matt as the first of the "chosen". Hannah arrives, and is injected with a sedative by the cultists. The cult begins a union ceremony between Matt and Hannah, but Hannah escapes. Rachel appears at the gathering, claiming Isaac is a false prophet. Morgan attempts to intervene to help Hannah, only to be bisected by Isaac with a machete. Gabriel flees, uniting with Hannah in a barn, where the two have sex. Matt proceeds to commit suicide by falling on a scythe.

Rachel is held captive in the hospital basement. Gabriel kills Jesse before Hannah confronts Isaac, who believes himself to be "He Who Walks Behind the Rows". Gabriel, using his supernatural powers, forces Cora to shoot herself, before confronting Isaac with the revelation that he was in fact the firstborn child of Isaac's cult, and that Isaac denied him his birthright in favor of his own son.

Gabriel instructs Hannah to kill Isaac, but Rachel urges her not to. He then reveals himself to be fully possessed by He Who Walks Behind the Rows. Gabriel restrains Isaac with his supernatural powers, killing him with a broken lead pipe. Rachel subsequently stabs Gabriel. Rachel and Hannah flee as Gabriel remarks that "The seeds have already been sown". Gabriel's wound miraculously heals itself, and he begins to set off explosions, killing Jake.

Hannah and Rachel leave on foot, walking down a country road. Hannah is unaware of what Gabriel's words meant—that she is currently pregnant with the child of He Who Walks Behind the Rows, continuing the cult's legacy.
