The Mirando Corporation created unusual piglets and distributed them to farmers around the world. For ten years, the giant experimental pig Okcha was Mi-ja's best friend; they lived peacefully in the South Korean mountains and took care of each other. But one terrible day, the idyllic life of the friends was interrupted - a corporation took their property. The bitchy general director Lucy Mirando has her own, not the most humane, plans for the unusual beast. Of course, the brave girl will not abandon her friend in trouble, and Mi-ja sets out to save Okcha, but the world turns out to be much crazier than she could have imagined.
