In the '50s, Bert I. Gordon made a career out of sci-fi movies about gigantic mutated insects (Beginning of the End, Earth vs. the Spider), lizards (King Dinosaur, Serpent Island), and even people (The Amazing Colossal Man), and in 1977, he was still up to his old tricks with this picture, loosely adapted from a story by H.G. Wells. Marilyn Fryser (Joan Collins) is a less than scrupulous businesswoman who is trying to sell shares in a worthless Florida housing development to a group of naive souls. However, both Marilyn and her potential customers have bigger things to worry about than low property values, when they discover that a large stock of nuclear waste was dumped near the development site, and the result is a pack of gigantic mutated ants with a nasty disposition and a taste for human blood. The supporting cast features Robert Lansing, John David Carson, and Albert Salmi.
