Future hunters capture superior animals to genetically engineer stronger creatures, having already secured a nearly extinct cheetah. They then travel ten thousand years into the past to hunt a mammoth. Atom and Uran are accidentally transported to this era, where Uran arrives first and is saved from hyenas by a primitive boy. Despite the language barrier, the trio forms a deep bond. Meanwhile, the hunters pursue the mammoth accompanied by monsters named Cyclops and Web. Upon hearing the cries of a baby mammoth, Atom decides to intervene and rescue the animal from the ongoing hunt.
