12-year-old Mully has lost his mother and discovers his debt-ridden father stealing the charity money they've raised in her name. Grabbing the cash, Mully steals a taxi and is shocked to find a woman, Joy, in the back seat with a baby. A straight-talking solicitor who didn't expect to get pregnant, Joy is struggling with motherhood and planning to give her baby to a friend who will raise the child as her own. She joins Mully on a wild journey across Ireland, stealing cars, hitch-hiking, catching ferries and breaking police barricades.
