在这部最后的警察喜剧/动作片中,故事始自1985，横滨中央署刑事课刑警京极浩介（唐泽寿明 饰）在执行任务时遭遇爆炸而陷入昏迷，这一睡便是三十年时间。2015年的一天，沉睡良久的浩介意外醒来，睁开眼后发现这个世界已经发生了翻天覆地的巨变。时代的进步让他恍如乘坐时光机而来的古代人，曾经相濡以沫的妻子加奈子（和久井映见 饰）也不知何时另外组建了新的家庭。在引出一番混乱后，他被年轻有为的青年刑警望月亮太（洼田正孝 饰）逮捕。在此之后，浩介得遇当年的后辈和上司，并借助他们的帮助重归警察队伍。有趣的是，他被分配成为亮太的搭档。
一个是凭借热血鲁莽前冲的粗暴大叔，一个是崇尚智力和科技的新世纪青年，他们将上演怎样的故事呢？

还是接受不了智商被侮辱。史上最烂的日剧，只能弃了~可惜了小唐！。
