While her son, Kichi, is away at war, a woman and her daughter-in-law survive by killing samurai who stray into their swamp, then selling whatever valuables they find. Both are devastated when they learn that Kichi has died, but his wife soon begins an affair with a neighbor who survived the war, Hachi. The mother disapproves and, when she can't steal Hachi for herself, tries to scare her daughter-in-law with a mysterious mask from a dead samurai.

As a result of nuclear testing, gigantic, ferocious mutant ants appear in the American desert southwest, and a father-daughter team of entomologists join forces with the state police officer who first discovers their existence, an FBI agent and, eventually, the US Army to eradicate the menace, before it spreads across the continent — and the world.

The war against the Bugs continues! A Federation Starship crash-lands on the distant Alien planet OM-1, stranding beloved leader Sky Marshal Anoke and several others, including comely but tough pilot Lola Beck. It's up to Colonel/General Johnny Rico, reluctant hero of the original Bug Invasion on Planet P, to lead a team of Troopers on a daring rescue mission.
