坡和地震时有发生,欣欣向荣的背后存在着隐患。但是,让矢的猛更担心的是地球上的人们居然对这些有可能引发怪兽的现象熟视无睹.面对此情此景,猛苦于自己无处诉说,他感到光凭自己的力量是不够的,综上所述的那些潜在危机必须引起人们的高度重视。

繁华的夜东京，灯火通明。突然间，从空中飞来了一头长着翅膀的可怕怪兽——吉格吉拉，地球再次面临一场浩劫。5年来（1975-1980），怪兽积聚了强大的能量，它吸收了人类所有险恶、肮脏、憎恨、怀疑等等邪恶的东西，因此怪兽具备了强大的攻击力。

作为樱毛岗中学的教师与UGM的战斗员，矢的猛又开始了新的一天。看见京子老师走出教学楼，矢的猛热情地迎了上去，笑容满面地想和她一起走段路。不料，京子老师说自己将要参加游泳讲座，而且时间紧迫，所以不一会儿就告别了矢的猛老师。正当矢的猛郁闷的时候，操场边传来了一阵打闹声，只见两个男生纠缠在一起，一群学生则在围观。矢的猛立即制止了打架。

一天晚上，有一个不明物体正超速飞向地球。UGM的雷达捕捉到这一讯息。原田、田岛和惠美立即对该物体的行踪进行跟踪观测。此时，大山队长想找矢的猛队员协助调查不明飞行物。可是，人呢？

已经是晚上了，但矢的猛老师依旧坐在办公室里仔细批阅试卷。此时，他正为博士同学的满分成绩感到十分欣喜。不一会儿，学校的门卫师傅走进来提醒猛老师时间不早了，再这么忙下去恐怕赶不上末班车了。矢的猛看了看手表，还真是晚了，连忙收拾没有全部改完的试卷准备回家继续批阅。看到猛老师如此敬业，门卫师傅禁不住一番称赞。

本集的学生明男就像《和未知的遭遇》中的主人公，认为自己在地球上并不幸福。因为自己不是地球人而是其他星球的人，所以和周围的人不一样。而看到了UFO的到来，便以为是来接自己的，如果去了那个星球自己就会幸福。但UFO来的目的不是接明男，而是攻击地球。一切都是明男自己的幻想。

本集对怪兽作战的准备部分大大增加了，尤其是大山队长拼命向上级说明无声作战的意义时的剧情，而且无声状态下的东京也被真实再现。不过消防车要求出动，群众要求开车，苏联大使要求飞机起飞的部违反规定的人出现（同《杰克》里的《电波》）。

以前不相信怪兽会出现的UGM，从第1集以来吃了不少亏，所以这次主动出击调查了。这集也是樱毛岗中学的学生第一次看到UGM队员的一集。 由于要对学生们保密，田岛队员便说自己和猛是朋友。
