Tired of being ignored by classmates, Newt and his two best friends decide to create Halloween costumes that will make them stand out and let them discover their "inner other.... who we would be if we didn't have to be us." But before Halloween arrives, 10-year-old Newt's world shatters: his football star brother, Chris, is knocked unconscious in the season's final game and lies comatose in the hospital. At the last minute, Newt fashions a superhero Halloween costume from Chris's old clothes and dubs himself Captain Nobody.
