Plot summary
Erin returns to the island, where Sarah shows her Mildred’s restored youth and that her blood burns in sunlight, concluding that Paul has been causing apparent miracles through the communion wine and that Erin’s consumption of it caused her pregnancy to disappear. Erin tells Hassan, who refuses to investigate the church, fearing further stigma. Erin, Sarah, and Mildred try to flee but discover the ferries have been sent away. That night, Sturge cuts power to the town as Paul reveals he is Monsignor Pruitt and presents the Angel to the stunned congregation.
Explaining they have consumed the Angel’s blood, Pruitt urges them to drink poison and be reborn. Several parishioners comply, including Leeza’s parents, Sturge, Ooker, and Ali. Mildred shoots Pruitt before the Angel attacks her. The resurrected churchgoers then attack those who refused the poison. Erin shoots Bev, and she, Hassan, Leeza, Sarah, Warren, and Annie escape. Many slain residents, including Ed, also resurrect, while the revived Bev and Sturge unleash the undead congregation on the town.
