One of these men is Robin Smythe. He tries to get Kate Flynn to be his wife but she still mourns her husband whom Smythe says died. But her son Sean, doesn't believe it. He sends messages out asking anyone who knows anything about his father to tell him. One day he and three young people are fooling around when they discover that they turned off their implant. That's when they go outside and someone answers Sean's message and tells him where his father is. So he goes out to find him But Smythe pursues him and brings his mother as leverage. And when the robots corner Sean he somehow manages to control them. So the Robots are curious why he can do that. So they tell Smythe to capture him. 真的是烂片么？换个角度其实是烧脑级科幻片。真是太烂了，简直把观众当弱智。难得的烂片。。。。一群智障机器人统治一群智障地球人。槽点太多以至于不知从何说起~~。熊孩子拯救世界。机器人与人的哲学。 三年前，外星机器人入侵地球，经过七天的战斗地球被完全占领。从此之后，机器人对人类严加看管，它们向人类头上安装了定位系统，一旦检测到人类走出家门便将其毁灭。除此之外，外星人雇佣罗宾（本·金斯利 Ben Kingsley 饰）等人类叛徒担任辅助管理工作。罗宾迷恋美丽的妇人凯特（吉莲·安德森 Gillian Anderson 饰），但凯特只痴心等待失踪的丈夫归来。罗宾口口声声称凯特的丈夫早已遇害，不过她的儿子西恩（Callan McAuliffe 饰）并不相信，男孩始终未放弃寻找父亲的努力。某天，西恩意外和康纳（Milo Parker 饰）等伙伴发现令定位系统失效的办法。 孩子们尝试着走出家门，这一变故也让推翻机器人的统治成为可能……
