Jack is born with his heart frozen solid on the coldest day in history. A wise midwife saves him by replacing it with a cuckoo clock. Now Jack must abide by three rules to keep his mechanical heart safe: never touch the clock's hands, master his anger, and never fall in love. He tries his best, but when he meets a girl named Acacia he falls in love, threatening the delicate balance of his artificial heart.
