A mad Soviet scientist, Doctor LTG, inspired by the powerful iron monster KV-44, sets out to create his own version of the legendary tank. But one mistake changes everything.
Left unfinished, the artificial intelligence awakens on its own — and an almost sentient robot is born. It calls itself KV-404. After escaping the laboratory, KV-404 meets the mighty KV-44 and dreams of becoming his battle partner. KV-44 wants nothing to do with the clumsy newcomer, but fate forces them to fight side by side to defend a Soviet fortress from a terrifying German super-weapon. Action, humor, and heart collide in this story of friendship, courage, and teamwork. Will two very different tanks learn to trust each other, save their allies, and defeat an overwhelming enemy?
