Woody, a pull-string cowboy doll, is the leader of a group of toys that belong to a boy named Andy and come to life when humans are not to be seen. With his family moving to a new house and having a birthday party for Andy, the toys stage a reconnaissance mission to discover Andy's new presents. Andy receives a space ranger Buzz Lightyear action figure, whose features replace Woody's position as Andy's best toy. Buzz does not know that he is a toy when Woody tries to convince him and thinks that he is a real space ranger. While the other toys befriend Buzz, Woody hates Buzz and he doesn't want Buzz to become Andy's best toy.
