Guy is a cheerful bank teller living the same routine every day in Free City, unaware that he is actually a non-player character in a violent open-world video game. When he meets Molotov Girl and puts on a pair of player sunglasses, he begins to see the game for what it really is. As Guy grows beyond his programming, he becomes the key to exposing a stolen game code, saving Free City, and proving that even a background character can choose his own story.
