Jean Duval, a renowned puzzle architect, is mysteriously summoned to Marrakesh by the veiled Madame Valencia to restore an ancient underground labyrinth. As he works on the intricate mechanical puzzles and chambers beneath her estate, Jean senses there's more to the project than mere restoration. After three months of meticulous work, Jean discovers the labyrinth's true purpose: it serves as a testing ground for selecting the Trustee of the Valencia Foundation, which controls billions in philanthropic assets. Madame Valencia reveals herself as Fatima al-Fassi, descendant of the labyrinth's creator, who has been searching for someone to restore the labyrinth to its original purpose after her husband Eduardo corrupted it. Jean accepts her invitation to become a candidate alongside four others, navigating the labyrinth not as its architect but as its subject. In the mirrored chamber at the heart of the maze, Jean experiences a profound transformation, understanding that the labyrinth tests not just intelligence but character and vision. Whether chosen as Trustee or not, Jean emerges forever changed, having learned that true power lies not in control but in service to others.
