Elena and Skylar are soaring through the sky. Suddenly, the munfuego that Elena played on when she was a kid gives off a fiery blast. Skylar tells Elena that during her forty-one year imprisonment a rock monster moved in and every time he gets angry the monfuego starts to erupt. Down below, it turns out that the rock monster, who's name is Charoca, is angry because some kids are taunting him. After they run away scared, Charoca notices that the monfuego is close to erupting and calms himself down which prevents the monfuego from erupting. Later, one of the kids and his parents go to Avalor Castle to complain about the monster to Elena and the Grand Council. Esteban wants Charoca to be thrown out of the Kingdom but Elena wants to try diplomacy first. Naomi and Luisa wholeheartedly support Elena's idea and Francisco agrees on the condition that she takes the Royal Guard with her. Elena takes only Gabe with her and they head to Charoca's home together. Elena's attempt at diplomacy fails because of Charoca's short temper and because Gabe pulls her away before she can get a chance to really try.
When they get back to the castle, Esteban convinces the Grand Council to vote for Charoca's expulsion from the kingdom, to Elena's dismay. Isabel runs up to Elena and shows her a rock she calls a monster rock. This makes Elena realize why Charoca is so mad. Elena heads to Skylar and tells him to take her to the monfuego. Naomi walks up and, upon hearing her intentions, decides to go with her. Elena arrives in the village close to Charoca's home and learns that they are stealing the monster rocks from Charoca, which is why he is so mad. Elena and Naomi take the rocks back to Charoca, who reveals that he is not a bad guy but someone who just has anger issues. Suddenly, Esteban appears and attacks which angers Charoca enough to cause the munfuego to erupt.
Back in the village, Esteban spitefully blames Elena for causing the eruption and leave to inform the Grand Council. Working together, Charoca, Elena, Naomi, and the Royal Guard stop the eruption and save the village. Charoca is hailed as a hero and a celebration is held in his honor. When Esteban comes back with Francisco and Luisa, the latter tells her they are proud of her for following her heart. Charoca gives her a flower as thanks for her kindness.
