Anxious to return to Mars, Martin (Ray Walston) risks exposure by taking his spaceship on a short test ride. Sure enough, he is immediately spotted and classified as a UFO. Worse, Mrs. Brown (Pamela Britton) allows the government to use Tim (Bill Bixby) and Martin's apartment as a sighting station just in case the spaceship makes a return appearance. The key to the solution of this mess resides in a handy supply of plutron, which Martin uses to his advantage to throw the authorities off the track.
