Nobita stumbles upon a mysterious stone tablet that points to an undiscovered continent hidden somewhere in Africa. Convinced this is his ticket to adventure and glory, he drags Doraemon and his friends into an expedition to find it. What starts as a treasure hunt quickly becomes something far more complex when they discover Peko, a small creature with surprising intelligence and an unexpected connection to the lost civilization they're searching for. The group faces dangers that test their friendship and courage: treacherous terrain, rival explorers, and secrets the continent has kept buried for centuries.

Peko holds the key to understanding what happened to an ancient society, and deciding what to do with that knowledge becomes the real challenge. It's a classic adventure story wrapped in comedy and heart. Fans wanting spectacle mixed with genuine character moments will find something here, especially those who appreciate how Doraemon balances humor with surprisingly mature themes about responsibility and friendship.
