Nintama Rantarou Movie

A shipment of saltpeter belonging to Shinbei's father falls into the hands of the Dokutake ninjas, who intend to use it in an absurd scheme to create medicine that will let them fly. Danzou secretly follows the stolen cargo and ends up inside the enemy's hidden headquarters, leaving his classmates to realize that both he and the shipment are in serious trouble.

Yamada and Doi rush to intervene, but Rantarou and the other young ninjas refuse to remain behind and launch a rescue attempt of their own. Their enthusiasm quickly creates even more people who need saving, drawing Rikichi and the rest of the academy into a chaotic effort to recover Danzou and stop Happousai's plan before it succeeds.
