In an event well beyond the imagination of the average mind, a jobless youth turns out to be the only one who can save the day for a film star of yore. When Joe D'Costa offers superstar Vicky Bhargav a ride to a film shoot on his dilapidated scooter, little does he imagine this rendezvous can direct him up the alley of good fortune. What begins as a crazy road trip turns out to be a game changer for the two men. Good Boy Joe is a comical narration of how two strangers end up bringing a glimmer of hope and joy in each other's downtrodden lives.
