Don't Mess with the 8-Year-Old Gambling Master (1970)

After gambling destroys his family, Owen devotes his life to bringing down the underground casinos that ruined him. But when death sends him back to the night he was eight, he returns with a lifetime of skill—and one chance to save his parents. His first victory leaves a casino boss broken and humiliated, but the real players are only beginning to show their hands. This time, Owen isn't betting on fate—he's dealing the cards.
