There was an obsession with radiation causing giant size mutation in animals in 1950s cinema. This is yet another tale of a rocket taking something up into space (wasps in this case). When the rocket lands the wasps becomes a giant monsters and starts killing everything in their path! Dr Brady (Jim Davis) and Dan Morgan (Robert Griffin) head to Africa to investigate. The path to the remote part of Africa known as Green Hell is tough though, with attacks by tribes of natives and poisoned streams.
Once Brady and Dan reach the village near Green Hell they discover the local doctor (Vladimir Sokoloff) is dead, killed by the monster. They head into Green Hell with the doctor's daughter Lorna (Barbara Turner) to face, and stop, the monsters...
A fairly standard monster sci-fi film, padded out with plenty of stock footage of African safaris. The monster special effects are suitably ridiculous and cheap looking. Fun nonsense if a bit generic.
