Toy Story

In a world where toys are sentient but pretend to be lifeless around humans, a group of toys, led by Sheriff Woody, are preparing to move to a new house with their young owner, Andy Davis, and his family. During the party for Andy's sixth birthday, the toys become concerned that Andy might receive a new toy that will replace them. Andy receives a Buzz Lightyear action figure, who believes that he is an actual Space Ranger and does not know that he is a toy. Buzz impresses the others with his electronic features and becomes Andy's new favorite toy, much to Woody's jealousy.
Two days before the move, Andy's family plans to have dinner at Pizza Planet, and Andy is allowed to bring one toy along. To ensure Andy brings him instead of Buzz, Woody tries to trap Buzz behind Andy's desk but accidentally knocks him out the window instead. Believing Woody pushed Buzz on purpose, the other toys rebel against Woody until Andy takes him into the car, with Buzz following. When the car stops at a gas station, Buzz furiously confronts Woody. The two fight, fall out of the car, and are left behind, but then manage to hitch a ride on a Pizza Planet delivery truck. At Pizza Planet, Buzz mistakes a claw machine for a rocket and climbs in, pursued by Woody. Sid Phillips, Andy's sadistic next-door neighbor, grabs Woody and Buzz with the claw and takes them to his house, where they encounter his mutant toys, made from parts of toys Sid has destroyed.
After evading Sid's dog Scud, Buzz sees a television commercial promoting Buzz Lightyear toys and suffers an existential crisis, finally realizing that he is a toy. He attempts to fly, but falls and breaks his arm off. After Sid's toys repair Buzz, Sid tapes him to a firework rocket, planning to blow him up the following day. Overnight, Woody helps Buzz realize that his purpose is to make Andy happy, reinvigorating him. The next morning, as Sid prepares to launch Buzz's rocket, Woody rallies the mutant toys to help him, and together, they come to life and frighten Sid, telling him to play nice with his toys from now on.
After Sid flees, Woody and Buzz pursue the Davises' moving truck, but Scud, who had been locked out of the house from the mutant toys' efforts, attacks Woody. Buzz jumps off the truck and fights Scud off, while Woody climbs up and pushes RC out to rescue Buzz. The other toys think Woody is harming RC and promptly throw him out of the truck. Woody and Buzz race after the truck on RC, but his batteries run out. Woody ignites the rocket strapped to Buzz, and Buzz opens his wings to sever the tape just before the rocket explodes. Woody and Buzz glide through the sunroof of the Davises' car, landing safely inside. On Christmas in the new house, the toys happily listen to Andy opening his presents, no longer concerned over new toys replacing them. When Andy receives a puppy however, Woody and Buzz nervously smile at each other.
