Cry Baby, een sterk maar gevoelig meisje, wordt naar een internaat gestuurd. Ze krijgt er al snel te maken met zeer strenge regels. Gelukkig heeft ze een beste vriendin die voor haar opkomt als ze wordt gepest door de andere studenten en leerkrachten. Met de hulp van haar vrienden en een engelachtige gids probeert Cry Baby de regels te veranderen.
