Another summer vacation is coming. Fat Tiger (voiced by Subaru Kimura) and Suneo (voiced by Tomokazu Seki) instigated Nobita (voiced by Megumi Ohara) to ask Doraemon (voiced by Wasabi Mizuta) to find a secret place that has not yet been developed by humans. During this period, a dirty puppy came uninvited and successfully helped his mother find the lost bag. He became the pet of Nobita's family and was named Bianbian. Bianbian used the satellite camera to take pictures of the mysterious stone statue. Taking this as an opportunity, Nobita, Doraemon, Fat Tiger, Suneo and Shizuka (voiced by Yumi Kakazu) formed a young African secret expedition team. They went through hardships along the way and almost lost their lives. When getting closer and closer to the giant statue, the friends unexpectedly discovered the secrets of Bianbian and a mysterious kingdom. The originally happy adventure turned into a dangerous war. Can they save that country? This film is adapted from the long-running manga of the same name by Fujiko F. Fujio.
