The Space Shuttle returns to earth, but some of the equipment brought back on it begins to behave strangely.
OK sci-fi alien invasion drama is foremost watchable for its good and imaginative special effects, but also has suspense and a welcome performance by Walter Koenig.
Maltin**1/2: "OK entertainment...Very low-budget production shows ingenuity in its special effects and imagination in the story, but dramatic values are highly valuable."
