In the dense jungles of Africa, a scientific experiment goes awry as authorities investigate reports of unusual insect activity around an unexplored area. Dr. Quent Brady leads the initiative, originally designed to study the effects of cosmic radiation on animals, using wasps as test subjects. However, when the rocket, intended to return data, malfunctions and crashes in the wilds of Africa, monstrous life forms emerge. Reports trickle back, revealing massive wasps terrorizing the local tribes. Dr. Brady, based in America, confers with his colleague Dr. Dan Morgan and they decide to travel to Africa to confirm and contain this alarming development.

Once in Africa, they employ the help of native guide Arobi to navigate through the harsh territory rife with dangers both natural and supernatural. The team encounters numerous indigenous superstitions warning them against proceeding, which they dismiss until coming across decimated villages and unmistaken traces of the enlarging menace their experiment has spawned. Along their journey, equipment malfunctions and unexpected obstacles challenge their mission. As tension rises amongst the group, their scientific pursuit turns into a desperate struggle for survival. As they delve deeper into the heart of the jungle, the boundaries between scientific curiosity and its ethical implications blur, setting the stage for a confrontation seeped in perilous adventure and relentless threats from the unknown depths of the jungle.
