A test rocket containing scientific experiments, including a wasps' nest, crashes in the jungles of Africa. Radiation from outer space infects the wasps, creating a hive of titanic atomic mutations as big as a house. These hideous creatures have an appetite for human flesh and proceed to munch their way across the dark continent. An expedition of scientists are sent to investigate the strange happenings and native disappearances. Volcanic thrills come rocketing to the screen as science once again creates mutations born out of the radioactive world of the Atomic Age.
