An orbiting satellite picks up a beautiful song being played on Earth. Moved by the song and facing an eternity of lonely obsolescence thanks to the incoming fate of being replaced by new machinery, the satellite decides it wishes to find the source of the tune, and so crashes down to the planet below, where it promptly turns into a teenage girl able to fly with Astro Boy-like rocket feet and fire her arms as weapons. Meanwhile, the songwriter behind the ditty is broken-hearted and so has been turned into a cow, akin to the farmyard beast fate that has befallen other broken-hearted folk. This has led to him and others like him being hunted by a human villain who uses a plunger to extract their organs, as well an incinerator machine that is fueled by the broken-hearted. Also, there is a wizard named Merlin who makes it his mission to assist the satellite girl and the cow, except Merlin has undergone his own transformation recently and happens to be a roll of toilet paper.
