A spy is brought back from cryogenic suspension after being almost killed in a plane crash returning from a mission to learn about a deadly new weapon being developed in the East. But the vital memories are being suppressed, so the authorities use ultra-advanced technologies to try to uncover the secret. 　　Masterful performances from Christopher George (as always) and newcomer Greta Baldwin make this William Castle Sci-fi adventure truly exciting, innovative, classic space adventure with a deep message and meaning. Monte Markham adds another polished performance to his long list of superb acting film and TV credits. The film is way ahead of its time 1968 and deserved Oscar recognition. A truly well made, beautifully acted gem. Christopher George one of the greatest 60s/70s tough action leading men gives another epic, dedicated performance that put to shame other so called major stars. To correct some imbecile comments it is the presence and acting ability of stars like Christopher George, Audie Murphy and similar leading action men that make a film watchable and memorable. 　　译文(3): 一名间谍在执行任务返回时，在一次飞机失事中差点丧命，随后被从低温悬浮中带回，以了解东部正在开发的一种致命的新武器。但重要的记忆正在被压制，因此当局使用超先进的技术试图揭开这个秘密。
