如果时光可以倒流，我们想如何重走过去的路？如果时光可以穿棱，我们是否想去遥远的未来？有一些科学家，一直为这个人类的梦想不懈努力着。亚历山大·哈德金博士(盖·皮尔斯 饰) 是美国哥伦比亚大学的副教授，1895年，他已人近中年，虽然在学校他并不受校长待见，但多年来他一直有一个梦想，那就是做一部跨越时间的时光机，让人们可以自由穿棱在任何时代。

经过无数次试验和持之以恒的努力，哈德金的时光机终于启动了，他带着自己的梦想遨游在时间隧道里，世界变迁正以惊人的速度，像一幅幅画卷在他面前一闪而过，他抵达了2005年的纽约，但却发现往日的图书馆已成了虚拟的人机互访系统，人们正在热烈地讨论在要月亮上建立新殖民地，他大吃一惊，赶紧来到了2007年一探究竟，但等待他的却是他从没见过的大月亮，原来殖民计划给月亮造成了巨大的伤害，月亮很快坠入了地球。它的碎片撞击着纽约的曼哈顿，路人四散而逃，躲进了防空洞。亚历山大立即来到遥远的802701年，在这里，他遇到了帮助他的朋友，在经历了生死劫难后，意外发现了莫洛克人和伊洛人背后的邪恶秘密。

If time It can be reversed, how do we want to go back to the past? If time can travel through edges, do we want to go to the distant future? Some scientists have been working tirelessly for this human dream. Dr. Alexander Hudkin (Guy Pierce) is an associate professor at Columbia University in the United States. In 1895, he was almost middle-aged. The unique time machine allows people to travel freely in any era.

After countless trials and persistent efforts, Hudkin's time machine finally started, and he traveled in the time tunnel with his dreams. The world is changing at an astonishing speed, like a picture scroll Flashing in front of him, he arrived in New York in 2005, but found that the library in the past has become a virtual human-computer interaction system, and people are actively discussing the establishment of a new colony on the moon. He was shocked. He hurried to 2007 to find out, but what was waiting for him was a big moon that he had never seen before. It turned out that the colonization plan caused great damage to the moon, and the moon soon fell into the earth. Pieces of it slammed into Manhattan, New York, and passers-by fled and took shelter in bomb shelters. Alexander immediately came to the distant year 802701, where he met his friends who helped him. After experiencing life and death disasters, he accidentally discovered the evil secret behind the Morlocks and Ilos.
