The Delicate Art of the Rifle

College student Jay (David Grant) is walking with his professor Max (John Kessel) when suddenly shots ring out. Seeing his roommate, Walt (Stephen Grant), calling to him from a nearby rooftop, Jay makes his way toward him, thinking he needs help. But Jay discovers that Walt is the shooter, convinced he's been stricken with a "metaphysical virus" going around that erases people from existence and memory. At first perplexed, Jay soon begins to wonder if there's some truth to Walt's story.
