An evil scientist (Overlord) invents a device that emits a radiation that controls the minds of the people within its range. He gathers a sizable percentage of the Earth on his initial attack, and conventional forces cannot counter-attack as they will also come under the power of the Zone if they enter. Earth's most powerful soldiers are united to combat the menace while wearing their Zone-resistant suits. Each Zone generator is biological in nature and grows to full size and capacity in a matter of minutes. Earth's free forces are faced with the challenge of destroying the generators while resisting the Zone-controlled forces, not to mention how easy it is to re-establish a control Zone. The good guys consist of 5 soldiers that are dropped into special missions by a Zone-resistant plane. The bad guys consist of about 6 guys that are specially treated by Overlord to be Zone-resistant (they still show the red blemishes and retain them whether in or out of a Zone-controlled area) while maintaining free will, and are supported by 'Zone Troopers' who wear a helmet that allows them to leave Zone controlled areas while remaining under Zone control. 老婆大人记忆深处的动画片。暴露年龄阅历的动画片。 可能是本片给人的感觉比较阴暗吧，或者是因为当年播出时间很短，大多数观众对《螺旋地带》印象不深。在炭疽热成为头版标题以及担心恐怖分子可能使用生化武器进行恐怖袭击之前，其实，早在80年代就已经有一部动画片对这一切进行了演绎。我们对于恐怖威胁最糟糕的设想在“螺旋地带”里成为了现实。在可遇见的未来，一个名叫“黑寡妇”的邪恶组织在全球释放了一种传染性病菌，可以控制人类的思想。这种生物剂在全球以螺旋形式传播，已经覆盖了近半个地球。感染地区都被标示成螺旋地带，感染的人类被称为“地带人”，是受到黑寡妇控制的无自主意识的奴隶。为了抗衡黑寡妇，一支被称作“地带骑士”的国际精英战队应运而生，由自由世界的各个国家组成。地带骑士从世界各国军队的特种兵中选拔。依靠特别制装甲以保护其不受细菌感染，地带骑士的使命是要从和黑寡妇和他们的邪恶势力作战中，解救整个世界。
