Curtis LaForche lives in a small town in Ohio with his wife, Samantha, and daughter, Hannah, a six-year-old deaf girl. 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 seemingly inexplicable behavior concerns and confounds 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.
