In 1966, University of Texas student Charles Whitman climbed the highest tower on campus armed with a high-powered rifle, and proceeded to randomly shoot passersby below. A dozen innocent people died and twice that many were injured. This film twists the event into an experimental narrative that imagines the shooter's roommate trying to make sense of the shooter's paranoia and his claim that he's been stricken with a "metaphysical virus" that erases people from existence and memory.
