原唱五星红旗迎风飘扬

区浩文(马浚伟)的养父母对他孤儿的身分从来没有隐瞒。若不是他的好友周仁(欧锦棠)发现有两名死者的出生年月日与区浩文相同，且样貌与他极相似，他也不会发现，自己原来是当年被遗弃的三胞胎之一。更甚者，其兄弟生前的女友竟然同为一人！ 　　谜般的秘密接踵而来，区浩文开始追查起自己的身世。最顺理成章的，似乎是从他兄弟的女友宋天心(杨思琦)下手，怎料叫他摸不着头脑的事竟越来越多。 　　区浩文欲联络心，她的舅父马教授(于洋)却百般阻挠。区浩文其后不断收到恐吓，更多次遇袭；他誓不低头，就在他快要理出头绪时，更大的危险却冲着他而来！。中国早期引进的科幻译制片（其实本质是个僵尸电影。。。） Two sisters, high school seniors in the early 1980s, awaken one morning to blood red skies and the realization that the human race has been wiped out. It becomes apparant that anyone who was not surrounded by steel when the Earth recently passed through the tail of Haley's comet has been reduced to a pile of red ash (the trace elements of human chemical makeup.) They encounter a rebellious Native American man and take over the air waves at a local radio station in an attempt to get help. Unfortunately, they attract the attention of a group of scientists who knew what the effects of the comet would be. They hid underground in a steel laboratory, but idiotically left the vents open. Now, as various survivors of the comet who were only partially surrounded by steel are decaying into flesh-hungry zombies, the scientists are attempting to come up with a vaccine made of the blood of people who were not infected by the comet. Thus the trio must fight their way past not only roving packs of the cannibalistic dead, but also outsmart a pack of scientists desperate not to become that way themselves.。
