La habitación de Fermat

Four mathematicians, including Lluís Homar as Hilbert, Santi Millán as Pascal, Alejo Sauras as Galois, and Federico Luppi as Fermat, are invited to a house with the premise of solving a great enigma, but are instead trapped in a room with walls that close in as they fail to solve puzzles. They must work together to escape, but one of them is revealed to be the mastermind behind the game, who staged the convention to avenge a past failure. As the group navigates the puzzles and the true nature of their host, they uncover secrets and lies that lead to a shocking revelation about their own identities and the true purpose of the game.
