In a magical place called the Congo, in the beautiful forests and jungles of Virunga National Park, lives a young female mountain gorilla named Miza. She was just like any other baby gorilla, riding on her mother's back, playing, taking naps. Then, one day, when Miza and her mother were out searching for food, Miza's mother disappeared, leaving her baby alone and frightened. Miza's father, a fierce silverback named Kabirizi and the leader of Virunga's largest family of mountain gorillas, sets out to find Miza.
