After receiving a mysterious letter, the player learns that the missing employees from many years ago may still be in the factory, so he once again sets foot in this eerie place. At the beginning of the game, the player enters the prison below the Playcare area, where a large-scale body modification procedure has been carried out and toys that are not suitable for working in the factory are imprisoned.

During the exploration, the player will meet some new toy characters, who act as allies for most of the time and guide the player through the prison and experimental rooms. However, things do not go as planned, and the ending is full of surprises and horrors. According to Poppy's plan, the player places explosives at a specific location in the factory foundation, trying to destroy the factory to rescue everyone trapped inside. But when the player returns to the safe zone, he finds that it has been destroyed, and the toy Doey has fallen into madness for failing to protect the other toys. He keeps switching between pain and accusations against the player.

It turns out that Doey is the only one whose consciousness was extracted from three children, one of whom has violent tendencies. The game's villain Prototype attacked the safe zone, most likely to distract Doey and control him. In the end, under Prototype's control, Doey was destroyed and Poppy lost a powerful ally.
