In this dreary metallic factory enclosure, automatons are forced to labour for the rulers’ profit. Failing to do so, means they will not have access to their wind-up keys in the Energy Tower. As clock-like automatons, not rewinding their gears means death. Charlotte, however, has had enough. Can she get a hold of her wind-up key?在一個齒輪世界裡，貧窮的上鏈機械人被富裕的機械人欺壓。只有工作的機械人獲准到上鏈大樓上鏈。故事主人翁Charlotte不能再容忍富裕機械人的殘酷，決定要搶回自己的鎖匙，以及她的自由。
