For generations, the peaceful cats have lived on the mythical island of Yenching in the Chinese sea, together with many other animals. Kay, the cat hero of the game, is an apprentice in martial arts. He was practicing in his master's Dojo when Minister Shun, lord of the mighty gorillas, attacked his home and dislodged the cat township. On a quest to protect them, Kay begins an amazing journey which takes him across the vast island of Yenching. Gradually, he begins to unravel the incredible secret that lies hidden in the volcano fortress of Minister Shun.
Some of the enemies are unable to control their actions as a result of having a special device fixed onto them by Shun's army, making them attack whoever the Gorilla army sees as a foe.
There is also many other animals (including Hares, Pandas and Frogs) who share the once-peaceful lands with the Cats and they are also under Shun's rule.
