When the sequel to a popular title is released to the public for a special beta test, a group of players eagerly log in to try out the new experience. What seems like harmless violence quickly turns all too consequential when the players realize the game's biggest error: They can't log out. Forced to battle their way through an endless army of monsters programmed to kill their avatars, the players must fight against the clock and find a way out of the game before the real world catches up to them.
