Nintama Rantaro the Movie

The movie follows the Dokutake ninja as they steal a shipment of saltpeter from Shinbei's father. They intend to use it to brew a medicine that will grant them flight and turn them into super-ninjas. Danzou, whose father was transporting the cargo, sneaks aboard and ends up at the Dokutake's hidden base. When Shinbei alerts the school, Yamada-sensei and Doi-sensei hurry to intervene-but Hagumi decides to act alone and tries to save Danzou themselves. Their plan quickly falls apart, leaving them in need of rescue as well. Luckily, Rikichi, Yamada-sensei's laid-back son, steps in to help. Soon, everyone joins the fray-but can Rantarou and his friends defeat Happousai before disaster strikes?
