忧伤不是你和他人好,是看到他人那么容易就可以替代我的存在,对我来说没有人可以像你,对你来说每团体都可以是我。 In this sci-fi chiller, a young woman's peace is shattered when she begins hearing loud screams in her head. They are the agonized wailings of an astronaut deliberately marooned upon the moon by a double-crossing experimenter. Soon the woman becomes possessed by the astronaut.
