Returning to school after the Christmas holidays and after their triumph in the Christmas football tournament, the Footballers face a very harsh reality: They are left without a coach, as Felipe and Alicia leave Soto Alto for Atlético Madrid, and they risk being left without a team, as their school faces financial difficulties and the administration decides to cut sports and artistic activities. Meanwhile, as the Footballers go through days of anxiety, the whole village is preparing to experience historic moments. It will host a major exhibition traveling around the world: the Treasures of Ancient Egypt! Mummies, royal jewelry, crowns and scepters of the Pharaohs, grave goods, and hieroglyphics will be exhibited in the dark basements of a large church, so that visitors feel like they are entering the labyrinth of a pyramid. The opening takes place amidst a crowd of people and journalists who have flocked from everywhere, and just as the Footballers and their class are being guided through the exhibition, something happens that no one expected with all the security measures that had been taken: a power outage and the theft of the most valuable exhibit. Our nine well-known friends, along with Greta, who becomes the tenth Footballer, secretly take on the task of solving the mystery of this incredible theft to recover the magical necklace "The Eye of Horus." Will they succeed? What dangers and adventures will they have to go through? Let's follow them.
