Synopsis

Doraemon and his friends decide to run away from home and travel back in time to the prehistoric era—70,000 years ago, when nobody else existed. There, they build their own perfect paradise and enjoy complete freedom. Eventually they return to the present day, but a few days later they encounter a caveman named Kukul. It turns out he was accidentally transported to the modern era, and worse, his tribe—the Hikari tribe—was attacked and abducted by the villain Giga Zombie and his Kurayami tribe while Doraemon's group was away. Realizing what happened, Doraemon and friends decide to head back to the primitive age to rescue the Hikari tribe. What unfolds is a grand adventure that takes them further back in time than ever before.
