Doraemon has been chosen to be special competitor in the Galaxy Car Race with the first prize of which is the granting of one wish for the winner. Nobita and Doraemon compete as a duo, with the former planning to wish for ears for Doraemon (who has been depressed over not having any ears) if they win. Their fiercest opponent is the dashing, handsome robot-cat racer Depon Alex, who mercilessly teases Doraemon for not having ears, but Depon may not be the one they really have to worry about.
