Dr. Connie and Sergant John have always dreamed of extraterrestrial life, but after meeting all-too-human aliens, their superiors force tests, interrogation, torture, and imprisonment onto the ETs, forcing another alien passenger, who had been presumed dead, to slaughter many of the Earthlings at the base where her crew mates were being held. This alien is revealed to be a vampire-like creature and is soon able to free her fellow passengers and run for the safety of their ship. However, Connie and John follow them out and soon find themselves aboard the alien craft, with no option of returning home.
