<P> After his release, 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 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 to find Hawk . </P> <P> Hawk advances to the final eight competitors in the double - elimination tournament before suffering his first loss, injuring his arm in the process . Afterwards, Cutler summons Hawk to his presidential suite and tells him that he has always been a loser, but offers Hawk a way out and a chance for a fresh start: $500,000 and a top of the line semi (even better than the contest's grand prize) on the condition that he stay out of their lives for good (at this point Hawk had already signed over custody papers) but Hawk refuses . He returns to the tournament with a much tighter focus and powers his way through the rest of the field to advance to the final match against Bull Hurley, who has remained undefeated . Michael then finds Hawk and apologizes for misjudging him, which gives Hawk the emotional support he needs to compete . After a titanic struggle, Hawk is able to conquer his old rival . As father and son celebrate, Cutler (who had followed Michael to the competition) looks on in silence and with grudging respect for all that Hawk sacrificed to get Michael back . A triumphant Hawk and Michael take their new truck and winnings and drive off to start a new life together . </P> <Ul> <Li> Sylvester Stallone as Lincoln Hawk </Li> <Li> Robert Loggia as Jason Cutler </Li> <Li> Susan Blakely as Christina Hawk </Li> <Li> Rick Zumwalt as Bob "Bull" Hurley </Li> <Li> David Mendenhall as Michael Hawk </Li> <Li> Chris McCarty as Tim Salanger </Li> <Li> Terry Funk as Ruker </Li> <Li> Bruce Way as John Grizzly </Li> <Li> Jimmy Keegan as Richie </Li> <Li> Greg Schwartz as Smasher </Li> <Li> Allan Graf as Collins </Li> <Li> John Braden as Col.
