Long ago in The Hidden Kingdom, animals and humans lived together in peace until the evil HighRoller convinced the animals that humans were their enemies. But there is hope, thanks to a rebel force of young heroes known as First Squad, consisting of Lin Chung, Mighty Ray, Mystique Sonia and Jumpy Ghostface. Together they will have to face off against a variety of fierce creatures, such as fire-breathing Ligers and magic lantern-wielding Zebras, if they are going to win back the kingdom.
