In the country of Arrothon, where supernatural abilities are deemed a grave threat and punishable by death, the King enforces this cruel decree. Among his six sons, Prince First secretly opposes the policy, believing it to be both unethical and inhumane, but keeps quiet, as he is an outcast within his own family. When the princes discover that they themselves are mutants, their revelation ignites chaos and fury from both the king and the public. Faced with the prospect of execution or exile, the princes must choose between fighting for their beliefs or fleeing to survive.
