Plot summary
After serving four years in prison for a drunk driving crash that killed a young woman, Riley Flynn returns to Crockett Island, a fishing village devastated by an oil spill. Having lost his faith in prison, Riley struggles to reconnect with the island’s devout Catholic community, including his parents Annie and Ed, his brother Warren, his pregnant former girlfriend Erin Greene, and parishioner Bev Keane. A young priest, Father Paul Hill, arrives as a temporary replacement for Monsignor Pruitt, who is reportedly on pilgrimage in the Holy Land. While out at night with friends Ooker and Ali, Warren sees strange movement on a remote island inhabited by feral cats, one of which is later mauled by an unseen entity. The next night, Riley sees a figure resembling Pruitt walking along the beach during a storm before it disappears. The following morning, hundreds of dead cats are found along the shore.
