Four girls who have the ability to transform into legendary warriors, called Mysticons, band together to save their realm from evil. Arkayna, Zarya, Emerald and Piper -- who all come from different walks of life -- are drawn together by a prophecy to battle evil and protect their homeland. As the unexpected heroes become epic warriors, they also become close friends while working together. The stakes are raised when evil Queen Necrafa is released from prison and embarks on a mission to destroy the Mysticons and their home, Drake City.
