A pint-sized Martian is contented but bored with life on his own planet, and decides to visit Earth for some fun. Unfortunately, the Earthlings jump to the conclusion that the Martian is a monster, to be captured or destroyed or both. Unaware that the "hideous alien monstrosity" everyone is searching for is himself, the Martian joins the hunt. It isn't long before he comes to realize that the grass is always greener (or redder) on the other side of the universe...and besides, he hasn't forgotten that gorgeous Martian girl he left behind.
