In a near future, many are addicted to
Avalon, a virtual reality shooter. In Avalon, solo players or
parties raid
levels populated with AI-controlled enemies and opposing players. Winners are rewarded with
experience points and in-game money, which can be exchanged for cash, allowing skilled players to make a living. As their brains
interact with Avalon directly, it places mental strains on players, and sometimes rendered them
catatonic. Ash, a famous player, plays solo since her party disbanded. After a Class A mission, the GM (Game Master) warns her of the next level's danger, and suggests that she join a party. The next day, a Bishop-class character breaks Ash's record time on the same mission. Ash tries but fails to learn about him or his
avatar. As she leaves the game terminal, the Bishop player watches her. Ash runs into former teammate Stunner. Murphy, their former leader, went after a hidden NPC in Avalon, a young girl nicknamed "ghost," and became comatose. The girl is allegedly the only gateway into the rumored
Special A, a mission where players cannot "reset" (a mechanic allowing people to abort mission without
their avatars being killed). Players who went after "ghost" never woke up from the game and became "Unreturned". Ash and Stunner visit Murphy at a hospital, where someone looking similar to "ghost" watches her. At home, Ash searches for words regarding Avalon, and the ghost. The search leads her to the
"Nine Sisters", another Arthurian legend reference. Upon entering Avalon, Ash receives an invitation to a meeting, and is ambushed by
griefers. They lured Ash there to rob her equipment. After she overpowers a player, the griefers' leader reveals that only the real
Nine Sisters – Avalon's creators – know how to access
Special A. They are interrupted by an attack helicopter which kills most of the players. Due to a
lag, its missiles teleport in front of Ash. She "resets" and leaves Avalon, saving her avatar. On the return home, people around Ash seem immobile, with the exception of a dog. At home, after preparing a meal for her dog, she realizes that it has disappeared. She hears the helicopter flying past. The next day, Stunner meets Ash. He relays a rumor that the ghost appears when there's a high-level Bishop present on the battlefield, so Bishop players are sought out by parties seeking to enter
Special A. Before becoming an Unreturned, Murphy was a Bishop player. At her house, Ash is visited by the Bishop player. He offers to form a party with her and she accepts. Ash arrives at the game terminal and tells the receptionist that she plans to enter
Special A to look for Murphy. Despite warnings from the receptionist and the GM, she enters the game. There, Ash meets the Bishop player, whom she suspects is working for the
Nine Sisters. Stunner arrives, revealing that he was helping Bishop recruit Ash all along. The party confronts the Citadel, a
boss. Stunner, Bishop and his summoned dummy players distract the Citadel, while Ash attacks its weak point. After the Citadel is destroyed, Stunner spots the ghost. He is then shot by an enemy. Before being forced out of Avalon, Stunner mentions the only way to kill the ghost. Ash kills the ghost, turning it into a gateway. Ash steps into the gateway and disappears. Ash "wakes up" from the game booth, which is put in her apartment, wearing civilian clothing and without equipment. Bishop contacts her, saying that she is in
Class Real. The only way to exit Avalon is to complete the objective: defeat the Unreturned staying there. Ash takes a provided gun and proceeds to her destination, an Avalon-themed concert by the
Warsaw Philharmonic Orchestra. En route, she moves through a bustling world, unlike the previous levels and the real world. At the concert hall, Ash sees Murphy, and they walk outside to talk. As she confronts Murphy about his decision to stay in the game, he states that he prefers the "reality" within Avalon. Ash mortally wounds Murphy, who urges her to stay, then disappears. Ash enters the now empty concert hall, and sees the ghost on the stage. Ash trains her gun on the ghost, who smiles. The words "Welcome to Avalon" appear on screen. == Cast ==
