罗伯特．怀斯导演的一部具有悬疑性的科幻片，描述美国一枚太空舱堕落墨西哥荒郊小镇上，导致镇民全部离奇死亡，仅剩一老一少受重伤未死。特别营救小组将他们救回实验室研究其病况，最终发现其中奥妙。 本片制作相当认真，气氛和映象亦有部分的杰出表现。但整体来说太过沉缓，描述科学家如何研究细胞分裂的过程也太详细了。When virtually all of the residents of Piedmont, New Mexico, are found dead after the return to Earth of a space satellite, the head of the US Air Force's Project Scoop declares an emergency. Many years prior to this incident, a group of eminent scientists led by Dr. Jeremy Stone (Arthur Hill) advocated for the construction of a secure laboratory facility that would serve as a base in the event an alien biological life form was returned to Earth from a space mission. Stone and his team - Drs. Dutton, Leavitt and Hall (David Wayne, Kate Reid, and (James Olson, respectively)- go to the facility, known as Wildfire, and try to first isolate the life form while determining why two people from Piedmont (an old wino and a six-month-old baby) survived. The scientists methodically study the alien life form unaware that it has already mutated and presents a far greater danger in the lab, which is equipped with a nuclear self-destruct device should it manage to escape.
