After their own solar system has died out, visitors in flying saucers hover above Earth. The aliens ask Earthlings (politely of course) to shove over and make room for them. Not understanding the message, Earth, with its usual flair for “shoot first ask questions later” diplomacy, opens fire, but in vain. Technologically superior, the aliens reveal their true intentions and send a last chance ultimatum to Earth before the final attack.
