Hidden away from the eyes of Equestrians, the prince Stone Hoof, Defender of the Downtrodden maintains peace and safety in his secret kingdom.

Far away in the north, his sister, Princess Ice Heart rules over a joyous secret kingdom of her own.

However, when an evil wizard threatens both kingdoms, they must team up to stop him before it's too late.
