Curtis LaForche lives in a small town in Ohio with his wife, Samantha, and six-year-old daughter, Hannah, who is deaf. When Curtis begins to have terrifying dreams, he keeps the visions to himself, channeling his anxiety into obsessively building a storm shelter in his backyard. His inexplicable behavior concerns those closest to him, but the resulting strain on his marriage and tension within his community can't compare with Curtis's privately held fear of what his dreams may truly signify.
