In the episode, Nobita and friends need a place for them to play, but because there is no safe place to play, Nobita wants to have his own town and world where he can do whatever he wants, whenever he wants, without anyone saying anything about it. Doraemon presents the "Instant Miniature-Making Camera", a camera that can create real miniatures form photos of objects. Nobita takes all of sorts of photos for his plan to make "Nobita Land."
