One night, the Nohara family were enjoying a pleasant dream, when suddenly a big fish appeared in their dreams and ate them. The next morning, Hiroshi read in the newspaper that everybody in another town had the same nightmare as him, but it seemed to have ended. But Hiroshi also heard the same dream from Misae, Shinnosuke, Himawari and even Shiro. They were surprised and thought if the same thing is happening in Kasukabe too. In kindergarten, on telling others about his nightmare, Shinnosuke was surprised to know that everybody too had the same dream. Then a mysterious girl named Saki was transferred to Futaba Kindergarten and joined Shinnosuke's class. Everyone in the class, including the rather inactive Bo-chan, were all excited and happy on seeing her. But Saki had a cold attitude and didn't get along well.

Todo comienza cuando Shin chan y sus amigos se dan cuenta de que las profesoras y compañeros se comportan más raro que de costumbre. Cuando comienzan a investigar, llegan a la conclusión de que la ciudad de Kasukabe se está llenando de clones. Aparece un ser idéntico a otro y sin que nadie pueda evitarlo, el auténtico desaparece por completo. Lo único que saben de estos clones es que les gusta bailar nada más y nada menos que... ¡la samba! Este dato les ayuda a adivinar qué personas de su alrededor no son auténticas; ya que una vez que suena la música ¡no pueden dejar de mover el esqueleto!
