Humanity abandoned Earth at the dawn of a new ice age. Over time, those who took control of the world were… rabbits!?
After humanity's departure, rabbits referred to humans as "giants" and worshipped the massive ruins left behind, calling it the "Chimney Mountain." Those who dared to violate and excavate this sacred site are known as "rust diggers."
The protagonist, an old rabbit named Stamp, is one of these rust diggers, whose daily activity consists of digging into Chimney Mountain.
One day, on his way back from exploring Smokestack Mountain, Stamp encounters a team of rust diggers known as "BB" and ends up joining them on a quest to delve deeper into the heart of Smokestack Mountain.
Along the way, Stamp discovers archives of ancient information storage devices called "D-TAM," scattered throughout the ruins.
One of these archives seems to belong to his daughter, from whom he is separated, hinting at the danger that threatens her and revealing hidden truths about the world he once believed in.
To unravel many mysteries and trace his daughter's path, Stamp continues his journey into the depths of the ruins...
