James (Kodi-Smit-McPhee) has shut himself off from his surroundings, falling into a world of imagination and darkness. Visits with his psychiatrist (Danny Devito) have proven unhelpful – though he takes a liking to fellow patient, Val (Isabelle Fuhrman). As James begins to rebel against his single mother (Virginia Madsen), he ventures into the night where he meets a mysterious kid (Evan Ross) who welcomes him into an eccentric city. Relationships are put to the test as James navigates unfamiliar territory, wrestling with the reality of his own personal wilderness.
