Liam was humiliated for touching his cousin's motorcycle, vowing to own his own. He built the "Iron Mule", won a bet against his cousin. Rejected by the local racing team, he completed an impossible race to join. He worked odd jobs, trained, and modified his bike, rising from local to provincial races, but was separated from his girlfriend by her family due to his poverty. Three years later, Liam is at the international dirt bike championship.
