A gang leader who is trying to start a turf war attempts to recruit one of Walker's karate students, Tommy Lopez, to his side. When Tommy refuses, the gang severely wounds his older brother, Ernesto, a former member of theirs, in a drive-by shooting and frames a rival gang who they had shot just moments previously for it, and Walker must stop the rival gang from retaliating and igniting the turf war, as well as prevent Tommy, who decides to join Ernesto's old gang to get retribution for Tommy's shooting (not knowing that they are actually responsible for it), from throwing his life away in an act of misguided vengeance.
