Synopsis: When Curtis (Michael Shannon) begins having nightmares of an encroaching, apocalyptic storm, he refrains from telling his wife, Samantha (Jessica Chastain). To protect her and their six-year-old deaf daughter Hannah, Curtis stars focusing his anxiety and money into the obsessive building of a storm shelter. While Hannah's healthcare and special needs education has resulted in financial struggle, Curtis' seemingly inexplicable behavior concerns Samantha and provokes intolerance among co-workers, friends and neighbors. However, the resulting strain on his marriage and tension within the community doesn't compare to Curtis' private fear of what his disturbing dreams may truly signify.
