One day, an alien (Ulli Birve) from the distant planet Epsilon materializes in the Australian outback. She's helped by a local surveyor (Syd Brisbane), who doesn't understand the alien's revulsion at being trapped on Earth. She explains that throughout the galaxy, humans are regarded as destructive creatures who are too ignorant to save themselves from certain destruction. Furthermore, she takes the surveyor on a time-traveling journey around the world to show him the effects of mankind's thoughtlessness.
