14世纪的朝鲜村庄里，素来有“不可杀”的传说。暴君当政，下令收集民间铁器制造兵器，农民们没了生产物资根本无法生存，村里的老铁匠因为擅自把铁器还给农民，自己被官兵投进大牢。老铁匠在牢里绝食，临死前用泥土和打翻的饭菜捏了一个玩偶，悲痛的女儿将玩偶拿回家，做针线活时不小心刺破手指，血滴在上面，玩偶活了起来。小东西吃铁为生，越长越大，铁匠一双儿女知道，这就父亲常讲的“不可杀”。“不可杀”长成一头巨兽，受姐姐驱使，在农民起义中帮助村人对付官兵，成了农民们的致胜法宝，不过迎来和平的村民发现，已经没有足够的铁供应给“不可杀”当食物，它会吃掉他们所有的劳作工具。英雄成了隐患，为了村民们的生存，姐姐流着眼泪挺身而出，献出自己的生命和“不可杀”同归于尽。
