The main characters of the cartoon are living toys that live in the room of their owner, a boy named Andy Davis. Every year, Andy gives new toys to his birthday, so for the old, this day becomes a source of great excitement, since the appearance of a new toy can promise oblivion of the old, after which they are waiting for either a garage sale or a dump. From the kindergarten, the boy's favorite toy was a rag cowboy named Woody, who in his secret life is the leader of the whole toy society and preaches that the toy has the meaning of life while it is played, and this is a reflection of the child's love for the toy. Another nightmare for Andy's toys is the neighbor boy Sid Phillips, who is entertained by breaking and remaking toys into monsters and is therefore a constant threat to them.
Andy's next birthday because of the rapid transfer of his family to a new house was decided to celebrate a week earlier. He was a terrible day in the life of Woody: a new toy, which was given to the child, took his place. This is a new super popular toy, Lightyear, an astro-ranger who has many different functions, like the wings opening behind his back and the laser beam emitted from his wrist. Woody loses its popularity not only from Andy, but also from the entire toy community. He is imbued with hatred for a new toy.
At the same time Buzz absolutely sincerely considers himself to be an astro-ranger, which is written on his box, and not a toy. Woody tries unsuccessfully to dissuade him in this. Andy and his mother, Mrs. Davis, and Molly's sister are going to the restaurant "Planet Pizza". He is allowed to take with him some toy, but only one. Fearing that Andy will choose Buzz, Woody decides to push his opponent unnoticed into the gap between the table and the wall, from which he will not be able to get out soon, but as a result Buzz falls into the window.
Toys immediately realize that Woody is guilty of what happened to Buzz. They are going to lynch Woody, but the arrival of Andy interrupts this action. Cowboy decides to at all costs save Buzz. Meanwhile, Andy, not finding Buzz in place, takes with her former pet, Woody, while thrown out on the street, clings outside to Mrs. Davis's car. Buzz and Woody meet at the gas station and start to sort things out, but the car with Andy leaves, leaving them both on the street. Thanks to Woody's ingenuity, both heroes almost overtake their owner in a popular children's restaurant, but suddenly find themselves in the hands of Sid Phillips and thus get to his home.
There they meet the mutilated Sid toys and take them for cannibals. Frenziedly looking around in search of an exit, Buzz sees advertising on his TV in his honor and understands that Woody was right - he is not an astronaut, but just a toy. A plastic astronaut makes a desperate attempt to take off, but when it falls, it loses its hand and falls into depression. Woody accidentally shows his hand to his friends toy-toys from the window and thereby finally convinces them that he allegedly killed the newcomer. Toys Andy refuse to help Woody and Buzz in escape. But then suddenly to the aid of the tandem come Sid's unfortunate toys, put the cosmonaut's hand in place and agree to help them in flight.
Sid decides the next day to stick Buzz to the mini-rocket and blow it up, but Woody and the rest of the toys save the astranger by attacking Sid and thus revealing his secret. Sid himself has a phobia to toys. In the meantime, Woody and Buzz notice the commuting in Andy's house and go after the truck with the things. They almost overtake him, but Andy's toys throw Woody back, not believing his words about Buzz and still considering him a killer. But then binoculars Lenny sees in the distance a living Buzz, and then the toys still with the help of the Spiralki doggy try to take them into the body.
Then follows the dramatic pursuit of the truck on a toy car, which is quickly discharged batteries. Then Woody launches Sid's missile, and she and Buzz really take off, having time to separate from the rocket at the last moment. The latter is happy, as he first truly flies, using his "cosmic" wings for his intended purpose.
Woody and Buzz, after the adventures that have become real friends, to great joy Andy fall directly to him in the seat through the hatch in the roof of the car Mrs. Davis. Christmas is coming. Toys are still worried about who this time will give Andy. But everything ends well: Molly gets Mrs. Murphy, and her brother Buster's puppy.
