A space module lands on Earth after a failed mission, but the astronauts have been replaced by hideous creatures that can penetrate people's bodies and make them explode. A group of speleologists are attacked by the alien monsters inside an underground cave, but the survivors are in for a surprise when they finally escape the trap.
