Doraemon constructed an underground cave hideout for all to enjoy, but Suneo went astray. The rest emerged from the cave without Suneo and later realized that the entrance had collapsed, leaving Suneo trapped. They must now seek out a new entrance and their journey leads them to a prehistoric realm inhabited by dinosaurs. Their rescue comes from Vanho, a warrior who not only frees them but informs them that he has discovered Suneo. However, when they locate Suneo, they uncover Vanho's people's sinister agenda. Their plan is to use Doraemon's group as specimens to examine and eventually conquer Earth's surface.
