Itzel, a young girl of Mayan descent, goes on a camping trip deep in the jungle with her father. As they stargaze together, Itzel's curiosity leads her to wander off and explore the surrounding area. While walking, she discovers a Jaguar in captivity and, without hesitation, frees the majestic animal.

However, their escape is short-lived as a furious poacher begins to pursue them. Itzel runs for her life, and in the process, she stumbles upon a mysterious lost Mayan city. As she explores the ruins, she experiences a vision of the city's glory days, guided by a magical Jaguar called Balam.

The adventure is full of wonder, danger, and magic, but Itzel is ready for whatever new discoveries the jungle and the stars have in store for her.
