A cargo ship filled with a unit of hi-tech edition Buzz Lightyear toys crash-lands on a deserted island. Stuck in demo mode, the shipwrecked Buzzes escape the island and follow the North Star to return to "Star Command".
Eight-year-old Bonnie receives a frog-themed tablet named Lilypad "Lily" from her parents in hopes of helping her socialize with children her own age. Bonnie soon becomes addicted to Lily and begins to neglect her toys. Jessie, as Bonnie's favorite and the new leader of her toys, explains to Lily about Bonnie's need for a real friend, which Lily attempts to solve by sending a friend request to Chelsea, one of Bonnie's classmates, on social media.
Fearful of losing Bonnie's affection, Jessie contacts Woody via a walkie-talkie for advice. Woody, who has left to help Bo Peep find homes for abandoned toys, decides to return to Bonnie, believing that Jessie needs help. When Chelsea invites Bonnie over for a sleepover, Jessie and Bullseye stow away in her suitcase while Bonnie takes Lily with her. Though she is initially happy to have them, Bonnie has her father take Jessie and Bullseye home after Chelsea, alongside her friends Heidi and Kara, question Bonnie for still playing with toys. Jessie and Bullseye escape but are found by an elderly couple. Seeing an old address written under Jessie's chaps, the couple takes the two back to the farmhouse of her original owner, Emily.
There, Jessie ends up in the shed of forgotten toys, including a potty-training device named Smarty Pants. As they enter the house searching for Bullseye, Jessie meets GPS receiver Atlas and camera Snappy. They inform her that a new family, the Manoukians—consisting of a young girl named Blaze and her parents—now inhabit the farmhouse. After experiencing a joyful playtime with an imaginative Blaze, Jessie decides to have her meet Bonnie and help them become friends.
Woody reunites with Bonnie's toys, and they confront Lily about Jessie's whereabouts. Believing the toys are hindering Bonnie's social life, Lily tricks Bonnie's father into putting them in storage while Woody and Buzz escape. At the farmhouse, Jessie works with the device toys to send a picture of herself to Bonnie in Blaze's name. Discovering that Lily's weakness is her speech recognition function, Woody and Buzz call out her name and force her to show the picture to Bonnie so that she can retrieve Jessie. They secretly hitch a ride as Bonnie and her mother go to the Manoukians'. Upon arriving, however, Bonnie rejects Blaze's offer to return Jessie and Bullseye after reading messages in a group chat, where Chelsea and her friends
ridicule her for still playing with toys.
Demoralized, Jessie sulks off to a tree where Emily used to play with her. She discovers a buried lunchbox filled with late-20th-century objects alongside photos of an adult Emily and her daughter, who is named after Jessie. Realizing she still had an impact on Emily's life over the years, Jessie regains her faith in Bonnie. Meanwhile, Woody and Buzz encounter the Buzz units, who happened to have landed nearby, and help them understand their true purpose as toys. With their help, along with the device toys, Jessie tracks down Lily, who boarded a donation truck out of guilt for hurting Bonnie. Jessie and the others catch up with the truck and convince Lily to help Bonnie befriend Blaze. Buzz professes his love for Jessie and they share a kiss.
The toys and devices arrange a new meeting between Bonnie and Blaze. After some hesitation, they bond over their love of toys. They play together and pretend to marry Jessie and Buzz, with Woody happily watching before he departs with Bo. Each of the Buzz units are later taken in by various children at a school playground.
