Luccas and Gi prepare for the biggest competition the Roxteen gang has ever faced. When they lose their sponsor, they will have to come up with the most outlandish ideas and participate in a gymkhana full of music and adventure to reach the Final Challenge.

Heir to the throne of the Kingdom of Lucebra, Prince Lu lives carefreely, playing pranks on his family and friends. However, according to legend, when he turns 18, he will confront the mysterious Evil Dragon and save the people of Middle Earth. Despite the prophecy, he doesn't believe in the imminent danger and prefers to "troll" his sister, the Enchanted Princess (Gi Alparone), and everyone working in the palace.

Luccas Neto, his sister Gi and their friends Vitória, Pedro and Jéssi had no idea what was to come on the school trip. When Luccas decides to invade the laboratory of the recently disappeared scientist Honório Flacksman, the group is sucked into a portal that takes them to another dimension – the City of Joy.

Luccas and Gi are separated for the first time in a competition at the camp. The girls and boys face off in a Talent Show for a spot in a real pop band. The trolling begins! Who's gonna do it best?
