In the submerged realm of Atlantis, colored-scale aristocrats oppress gray-scaled laborers who perform backbreaking chores. To shield her infant daughter Alice from assassins, Queen Diana magically cloaks the girl’s iridescent scales, letting her grow up as an impoverished servant. On Alice’s eighteenth birthday, sadistic nobles attempt to scrape her scales off in public, abetted by her cowardly boyfriend seeking elite patronage.
The Queen arrives with royal guards just as Alice's rainbow luminescence erupts, exposing her true lineage to the stunned court. Alongside heroic General Arthur, Alice leads an uprising against corrupt ministers secretly harvesting commoners' souls for illicit dark magic. Alice must harness her primordial oceanic powers to defend the underwater capital from imminent ruin.
