Andy, the owner of the toys, is 17 years old, and is about to usher in an important stage in his own life-university. At the same time, this change is also of great significance to his toys, and perhaps it will change the fate of all of them. Just as Woody and Buzz Lightyear were worried about the future, Andy decided to still keep all his toys, and took Woody to the university with him, putting the rest in the attic. However, Andy's mother accidentally threw the toy box into the garbage. When the toys realized that they were in the trash, they all thought that Andy had abandoned them. Jesse now called on everyone to take control of their own destiny and start a new life.
So the toys jumped into a box going to the daycare kindergarten. At the same time, Woody, as the only "pro-accompany" of Andy, was not put in the box. When he realized that everyone was missing, he began his own rescue operation. But unfortunately, in the end he himself was also trapped in the box.
Toys come to the kindergarten. The ignorant children can’t wait to reach out their dirty hands to these new toys. The tortured toys want to change places, but they find that they have no personal freedom in the kindergarten. Toys "Big Bear" controls the destiny of the kindergarten toys. Hu Di, who had left, learned of the situation of his partners and decided to leave the kindergarten with them and return to Andy's side. They were united in one mind and began to brew a great escape plan. Of course, what they will face is an extremely thrilling adventure.
