They must solve puzzles given by the host, who calls himself "Fermat", in order to escape the slowly closing walls of the room.

A stranger using the alias "Fermat" invites several people to attend a convention of the country's best mathematicians.

Upon receipt of the correct solution, each receives as an alias the name of a famous mathematician or philosopher; they are forbidden to reveal their true identities.

Each is instructed to arrive at a specific place and time, alone and without a cell phone, to work on "the greatest enigma".

After dinner, Fermat receives a phone call about his daughter, whom he claims is in a coma at a nearby hospital.

Galois, who previously gained press attention for allegedly proving Goldbach's conjecture, confesses that he lied to win back Oliva; the publicized sabotage of his presentation was staged to hide his failure.

Hilbert reveals that he is the mastermind, that he has spent his entire professional life trying to prove Goldbach's conjecture and was insanely jealous that Galois beat him to the proof; he staged this "convention" to avenge himself.

Pascal grabs the folder and scatters the pages upon the river, remarking that the world is still the same with or without the proof.
