In the New Mexico desert, Police Sgt. Ben Peterson and his partner find a child wandering in the desert and sooner they discover that giant ants are attacking the locals. FBI agent Robert Graham teams up with Ben and with the support of Dr. Harold Medford and his daughter Dr. Patricia 'Pat' Medford, they destroy the colony of ants in the middle of the desert. Dr. Harold Medford explains that the atomic testing in 1945 developed the dangerous mutant ants. But they also discover that two queen ants have flown away to Los Angeles and they are starting a huge colony in the underground of the city. When a mother reports that her two children are missing, the team and the army have a lead to follow. Will they arrive in time to save the children and destroy the colony?

In 1998 Joan Weldon
revealed that the temperature reached 110 degrees Fahrenheit (43 degrees Celsius) during filming, and she and Edmund Gwenn
were wearing wool clothing. Gwenn struggled with advanced arthritis. Although unnoticeable to audiences, he was in pain and was helped off-set by his valet. See more
Dr. Medford tells General O'Brien and the others that the giant ants forage "only between sunset and dawn, when it's cool", which is in conflict with the fact that it is still broad daylight when they encounter the first foraging ant. See more

I don't know.
Dr. Harold Medford
Nobody knows, Robert. When Man entered the atomic age, he opened a door into a new world. What we'll eventually find in that new world, nobody can predict.
