The reality of 2045 is not optimistic. The world is on the verge of falling and plunging into chaos. Wade Watts (Tye Sheridan) feels that he is alive only when he escapes to OASIS - a virtual universe where most people spend their days. In OASIS, you can travel, experience adventures and be whoever you want. The only limitation is your own imagination. The eccentric genius James Halliday (Mark Rylance), who created OASIS, is looking for a worthy successor. It organizes a three-stage competition, in which the prize is a huge fortune and total control over the universe. Wade and his friends known as the "Big Five" take up the challenge of looking for treasure in a curved reality. In a fantastic world - full of surprises, but also dangers - their task is more important than the competition itself. They must save OASIS and the whole world.
