Nate takes his family for a camping trip to reconnect. When they pull off at a rest stop, a gang of thieves hides their stash from an armored car robbery among the family belongings. They soon find themselves on the run and the gang will stop at nothing to get their money back.

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.
