One day in the city, a dog encounters a teenage boy eating corn chips. Irritated by the dog's begging, the teenage boy slaps the dog away, sending it flying to crash into a pile of garbage. Mockingly, he licks his fingers, only to discover that he has a hangnail. He attempts to bite himself off the hangnail, but he ends up accidentally tearing the skin off of his arm. In an act of vengeance, the dog tears the rest of the teenage boy off his skin, which exposes his entire body muscles. The film ends with the teenage boy screaming in pain.
