Fourteen-year-old Ponyboy is a "greaser": a boy from the wrong side of the tracks. Because Pony is a "greaser", he has to watch his back. The "Socials", a group of rich kids, enjoy beating up on "greasers." He lives with two older brothers as a result of their parents' deaths in a car crash. Pony's loyalty to his brothers and his gang is something rarely seen today. Then one night, his best friend,Johnny, makes a terrible mistake to save his and Ponyboy's lives- and it changes both of them forever.
