The Last Battle(La ultima batalla)

A group of boys, roughly seven to eleven years of age, go skinny-dipping in a river near their small Mexican town one afternoon and there find themselves the butt of an old vagabond's practical joke, the man stealing all their clothes from them. Humiliated about having to walk home in the buff, the tykes decide to get even, declare war. Yet, as the generations battle it out, a mutual respect develops, the depth of which is evident once the man has a heart attack during one of his romps with the kids. Will the boys' older pal recuperate so that they can engage in one final battle.
