Spoiler alert! Please do not read the following plot summary if you have not seen the film.Teenager Wade Watts lives with his aunt in Oklahoma City[8] in the "stacks", a poverty-stricken district constructed of trailer homes piled on top of each other. He spends his spare time as a "gunter" ("egg hunter"), logging on to the OASIS as an avatar under the moniker Parzival, reading Halliday's journal Anorak's Almanac, and researching details of the 1980s pop culture, mainly classic video games and movies, that Halliday loved. One day, he realizes that the first key is located on the same virtual world as his own online high school, in a re-creation of the Dungeons & Dragons module Tomb of Horrors. He meets Art3mis, a famous female gunter and blogger who has been exploring the place, and advances further than she does when he defeats the AI Acererak at the video game Joust. He is awarded the Copper Key, and Parzival appears on the "Scoreboard", attracting the world's attention.

Parzival completes the gate's puzzles by playing through the Dungeons of Daggorath video game and then role-playing Matthew Broderick's character in the film WarGames. Art3mis clears the gate shortly afterwards, as does Wade's friend Aech. Wade’s fame enables him to make a living by endorsing virtual products. It also brings him to the attention of Nolan Sorrento, head of operations at Innovative Online Industries (IOI), a multinational corporation bent on a well-funded effort to find the Easter Egg in order to take control of the OASIS and monetize it. When Wade refuses to join IOI, Sorrento attempts to kill him by blowing up the stacks where Wade lives, disguising the explosion as a meth lab accident.

Wade escapes and moves to Columbus, Ohio, where he lies low, assuming the pseudonym Bryce Lynch and living in an anonymous apartment designed for hardcore OASIS users. He considers an alliance with Aech, Art3mis, and Daito and Shoto, two Japanese gunters who have also earned the Copper Key. Instead, he and Art3mis begin a wary friendship, but when he asks her out, Art3mis declines. IOI operatives, called Sixers, attempt to assassinate Wade and Art3mis at the birthday party of OASIS co-founder Ogden Morrow. They are stopped by Morrow, who has special privileges and powers within the OASIS. Five months pass. Neither Wade nor anyone else has found the next token, the Jade Key.

When Art3mis finds the Jade Key, Parzival scrambles to planet Archaide, where he plays a perfect game of Pac-Man, receiving only a quarter as a prize. Aech provides a hint leading him to the planet Frobozz where he solves the text adventure game Zork. Sorrento, who had tracked Art3mis and Aech using a premium locator artifact, establishes a base there to farm their company's avatars with keys, and unlocks the second Gate and acquires the Jade Key. Shoto tells Parzival that the Sixers infiltrated Daito's real-life apartment and threw him out of the building, killing him.

Parzival unlocks the Jade Gate, a Voight-Kampff machine in the Blade Runner universe, and completes the arcade game Black Tiger as a character from the first-person shooter perspective. Using his knowledge of Rush, he acquires the Crystal Key, and after playing "Discovery", the third movement from the title track of their album "2112", finds a clue regarding the conditions to unlock the final gate. As he messages Art3mis, Aech, and Shoto with his solution, Sorrento ends their covert attempts to clear the third gate, Castle Anorak, and places a force field around it.

Wade manipulates his assumed identity in order to be arrested and placed in indentured servitude in IOI's tech support department. While inside IOI, he uses black market passwords and security exploits to hack into IOI's intranet: he acquires a wealth of information, including footage of Daito's murder. The information also includes the attempt on his own life, as well as plans to kill Shoto and Art3mis in real life. After escaping the corporation, he shares his information with his friends and publicizes a gathering of avatars to storm the castle. They are interrupted by Ogden Morrow, who offers them a safe haven at his home in Oregon. Wade meets the real-life Aech and Ogden, but not Art3mis and Shoto, who are already hooked into Ogden's immersion pods.

The day of the battle, Wade uses his planted hack to bring down the barricade, and a massive fight among avatars ensues. After Parzival uses the giant robot Leopardon to fight against Sorrento's Mechagodzilla Kiryu, Parzival and friends unlock the gate, at which point the Sixers use an artifact called the Cataclyst to destroy the castle and all avatars over a large area. Parzival survives because having the Pac-Man quarter granted him an extra life. As he enters the Crystal Gate, he announces that if he wins he will share his fortune with his three friends. With Sorrento and his Sixers on his heels, Parzival plays Tempest, role-plays King Arthur and various characters in Monty Python and the Holy Grail, and retrieves the Easter egg in Adventure. His victory grants him control of the OASIS, including wiping out his enemies' avatars, resurrecting his friends, and a Big Red Button that would wipe OASIS. Sorrento is arrested for the murder of Daito and for conspiring to kill Wade and the others. Back in Oregon, Wade and Art3mis meet in person and rekindle their relationship with a kiss.
