Digimon are using a chain letter to multiply in great numbers. Kiyoshiro receives the same chain letter and deletes it, but it ends up spreading to many others. Hiro and the gang must stop the Digimon before they overrun the city.
The midsummer day sings
Die Mittsommertage singen.
Los días de verano cantan
Los días de verano cantan
Les jours d’été qui chantent
Um dia de verão canta
под звуки летнего дня.
