Plot

A team of scientists are trying to perfect a weather-controlling system. Their efforts are hampered by the arrival of a nosy reporter and by the sudden presence of giant praying mantises. A reporter, Maki Goro, arrives on the island to find the scientists somewhat stir-crazy from the events, and is allowed to stay as a maintenance worker. Whilst there he also glimpses a mysterious woman the scientists were unaware of, apparently living in the jungle. The first test of the weather control system goes awry when the remote control for a radioactive balloon is jammed by an unexplained signal coming from the center of the island. Eventually finding the woman, Saeko Matsumiya, she is revealed to be the daughter of a previous researcher on the island who warned about a gigantic species of spider. The balloon detonates prematurely, creating a radioactive storm that causes the giant mantises to grow to enormous sizes. Investigating the mantises, which are named Kamacuras (Gimantis in the English-dubbed version), the scientists find the monstrous insects digging an egg out from under a pile of earth.
