Johnny Kelly (Michael Keaton) lives a double life: at home, he’s the good apple, looking after his ailing mother (Maureen Stapleton) and sexually obsessed brother, Tommy (Griffin Dunne). But his not-so-secret life is as Johnny Dangerously, an up-and-coming criminal being groomed by local gangster Jocko Dundee (Peter Boyle).
