Sigma Lady, who came from outer space, usually protects the peace of the earth as a member of the Earth Defense Force, Kamishiro. One day, she visits the Cosmo Tower, which was developed as a countermeasure against monsters. This facility is a huge tower built by the Ministry of Defense at the southern and northern ends of Shinagawa Ward, where many monster attacks occur, as an anti-monster trap. The towers are 620 meters high, and on their rooftops are devices that fire electromagnetic nets to capture the monsters. At the same time, the Mykars aliens, who are plotting to conquer the earth, are secretly planning to eliminate Sigma Lady! They kidnapped the Kamishiro team members, created fake Sigma Ladies from their DNA, and began to destroy the city. Sigma Lady fights to the death against the fake Sigma Lady, but is accidentally captured by an electromagnetic net launched from the Cosmo Tower.
