An unidentified object comes crashing to Earth after colliding with an American satellite, and when the President learns the object contains alien remains, he orders it hidden so as not to rile up the public while he runs for reelection. But two astronauts, Bancroft (Gary Collins) and Price (James Hampton), saw the collision and aim to uncover exactly what is being kept secret in Hangar 18. Robert Vaughn co-stars in this sci-fi cult classic.
