The film was directed by series co-developer Miguel Puga and stars the show's regular voice cast with the addition of Paulina Chávez, Angélica Aragón, Kate del Castillo, Cristo Fernández, and Sergio Aragonés.

The story follows newly minted twelve-year-old Ronnie Anne and her family as they go on a trip to Mexico and face off against an ancient preteen demigoddess.

City girl Ronalda "Ronnie" Anne Santiago intends to celebrate her "Summer of 12" at Xtreme Eddie's with her best friend, Sidney "Sid" Chang, but her family surprises her with a trip to Japunda, Mexico, much to her dismay.

However, during the trip, Ronnie Anne takes interest to a necklace that a shopkeeper claims to hold the last connection between humans and gods, but her mother, Maria, dismisses it as a hoax.

Her uncle, Carlos, tells her that the mountain is named after the petrified form of the demigoddess Punguari whose parents denied her from becoming a full-fledged god due to her rebellious nature and lack of responsibility.

Later that evening, Maria expresses her frustration about Ronnie Anne's rebellious nature, prompting Mama Lupe to take her outside to practice her chancla throwing.

Lupe's housekeeper, Don Tacho, crashes the plane he was piloting into the minions, taking them out, and each Casagrande utilizes their strengths to fight them off.

Punguari seals the cracks using the temple she built, preventing Ucumu's return and reunites with her parents Sisiki and Chipiri, who had been turned into gemstones.
