Earth transforms into a living canvas for intergalactic graffiti artists who want to plug us into a power grid and use us as living batteries even though they smell really bad who derive their sustainance by the army, navy, air force, space force and/or marines but one cunning young man somehow convinces them that people are okay and they are taken in by a kindly old lady who mistakes them for lost children.
The End.
