When America's first female astronaut (guest star Farrah Fawcett) runs into trouble, Steve tries to help, but discovers that his powers are limited by space travel.

A UFO carrying four anthropomorphic aliens seeking a new home on earth crashes into the ocean. The aliens manage to escape their lost vessel and swim ashore. Having witnessed the UFO’s flight, Steve Austin investigates a town close to the point of impact. Things quickly turn confrontational when physical contact between an alien and a human causes the alien to slowly die and the human to suffer radiation burns. Steve Austin befriends the aliens and attempts to assist the sole survivor in returning to her people before she dies. Despite astronomical odds, an impending rocket launch appears to be the only possible solution.
