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?

The camera Dr. Pat Medford (Joan Weldon) was using in the helicopter was a Stereo Realist, which was a 35mm format stereoscopic (3-D) still camera. This is both perfectly natural and ironic, since the film itself was originally planned as a 3-D release. See more

None of the ants previously seen by man were more than an inch in length - most considerably under that size. But even the most minute of them have an instinct and talent for industry, social organization, and savagery that makes man look feeble by comparison.
A 2-3 minute segment following the projection sequence was excised from the film in the mid-50s following a lawsuit from a real-life scientist whose name was used in the story for a fictional explanation of atomic energy effects on ants. The scene was removed from the negative and has not been restored though it has turned up in some collector's prints. See more
