本片描述了由让.雷诺和克里斯蒂昂.克拉维埃饰演的戈德弗鲁瓦骑士和他的侍从拉弗里普伊两人因巫师的失误由公元1122年被抛送到现代。他们被电话、汽车、洗澡间等等现代化的设施弄得惊讶不已,从而演出一系列笑话。导演让-马力.普瓦雷善于突出并发挥演员的作用,注重对诙谐文字、滑稽剧和高卢幽默的兼收并蓄。本片“玩"的是长达千年的“时间差",充分利用了张冠李戴和过时的习俗,围绕中世纪来客面对现代电子世界的丑恶遭遇产生的惊讶来做文章。它完美地运用了大量特技效果,故成一部滑稽惊险喜剧。Marine scientist Fred Miller designs the world's first underwater home, but when the business magnate funding his work threatens to end the project, Miller volunteers to live in it with his own family to prove it's practical. The underwater clan includes his water-phobic wife and his daughter and son, who are part of a rock and roll band. They bring along the lead singer and drummer. Along the way, they have to contend with a competing engineer who promises to mine the ocean floor for the businessman. A record producer likes their music and books them on TV, leading the kids to try to escape to the surface.。
