Joshua

Brad and Abby Cairn are an affluent New York couple with two children. Their firstborn, a self-decided conservatively dressed 9-year-old, Joshua, is a child prodigy on the piano and demonstrates ability to such a degree that he thinks and acts old before his time.

Joshua gravitates toward his oblivious Uncle Ned as a close friend, but distances himself from his parents, particularly following the birth of his sister, Lily. As the days pass, bizarre events transpire as the house regresses from healthy and happy to strange and disorienting. As the baby's whines drive an already strained Abby to the point of a nervous breakdown, Joshua exhibits downright sociopathic behavior, while Brad finds he can't help his wife, do well at his demanding job, or match wits with his strange son.
