Hawk leaves to compete in the World Armwrestling Championship in Las Vegas. His hope is to win the grand prize of $100,000 and a brand new, larger $250,000 semi-truck and thus start his own trucking company. Hawk is a clear underdog, having a size disadvantage versus just about every other participant, including his old rival Bull Hurley, who is the odds-on favorite out of the other 500 competitors. When he arrives, he sells his truck for $7,000 and uses the money to place a bet on himself (as a 20–1 long shot) to win the tournament. Meanwhile, Michael finds all the letters that Hawk had sent over the years and realizes that his grandfather has been hiding the truth about his father from him. Cutler did everything possible to drive his parents apart and had been intercepting and hiding the regular letters Hawk had written to him. Stunned by his grandfather's deceptions, Michael steals one of his grandfather's many vehicles (a pickup truck) to go to Las Vegas and find Hawk.
