The year is 1990. An alien species makes contact with Earth through radio transmission, notifying of an imminent visit. Alien ship crash lands on Mars, and a rescue team is sent out from Earth. (The plot thickens! :) Eventually a surviving female is located and brought on to the human ship. The female is light green with an amazing hair-do. After some unsuccessful attempts by the human crew to feed her, she is more or less left to herself. (Ominous, is it not?) While most of the crew sleeps, the Alien female hypnotizes the astronaut on guard. When the crew awakens, she is sleeping, and the guard is DEAD!
