Woody (voice of Tom Hanks) and the rest of the toys are back for an all-new adventure, welcoming new friends to Bonnie's room. One new toy is Forky (voice of Tony Hale), for whom Bonnie feels a special affinity because she made him herself from a spork during art class at school.
However, Forky doesn't consider himself a toy, so he runs away. For Bonnie's sake, Woody goes after him to bring him back. Along the way, Woody bumps into his old friend Bo Peep (voice of Annie Potts), who introduces him to a colorful amusement park. Back at home, Buzz Lightyear (voice of Tim Allen) and the rest of the toys get worried when Woody and Forky don't come back.
