Max Bernal (Bobby Cannaval), a former successful late-night comedy writer and later a less successful stand-up comedian, recently ruined his career and marriage when he moves in with his father (Robert De Niro). When he and his ex-wife Jenna (Byrne) discover that they disagree on how to address the needs of their 11-year-old autistic son Ezra (William Fitzgerald), Max decides to kidnap his child and take him on an adventure across the country, with comically disastrous consequences.
