In 1962, Burt Munro is a sort of folk hero in his home town of Invercargill, New Zealand, known for his friendly easy-going personality, for having the fastest motorcycle in New Zealand and Australia, and for being featured in "Popular Mechanics" magazine. However, that recognition is contrasted by his exasperated next-door neighbours, some of whom are fed up with his un-neighbourly habits; such as revving his motorbike early in the morning, urinating on his lemon tree, and not mowing his grass. Burt, however, has a long-time dream; to travel to the US and test his motorbike's capabilities at the Bonneville Speedway.
