A scavenging alien race travels from planet to planet enslaving their populations and stripping the hosts of all its resources. A unit of four aliens, who can masquerade as humans, is sent to scout Earth and discern whether or not their mind control techniques will work on the human race. If they fail to control the humans, the aliens will destroy the race and strip mine Earth for its raw materials. As part of the experiments, four humans are kidnapped and brought aboard the alien ship for testing. The abducted humans are sorely tested as they battle the aliens in a fight to get back to Earth and save the planet and its inhabitants.
