A dog carcass, a dump and beautiful moths high in the sky. This is the life of Steve, a parasite desperately in search of a soul mate. Unfortunately, his attempts to be close to someone always end in disappointment: The bird he saves from another dog dies; the rat that touches him dies; the cockroaches, pretending to be his friends, take everything from him but the last bone. Absolutely helpless in the skeleton of a former wearer, he almost loses his life under the wheels of an evil combine harvester, but at the last minute, the bird from the beginning of the story re-appears to save him. But it is not really the same one: Another parasite is now living inside the bowels of the dead bird. Steve has finally found his soul mate. Together, they pupate and soon fly off as moths into the night sky.
