A fascinating, modern-day retelling of the urban legend of the doppelganger, Simon Heath's play is an intriguing story where physics, psychology and basic human instinct collide. Doppelganger is the story of two office drones--a network engineer, George, and a human resources executive, Marcia--coming to terms with the sudden death of their mutual acquaintance, Frank. Frank dies by falling from his office window to his death while joking with George. Simultaneously, the same Frank is having an affair in the office across the street with Marcia. Time and space play tricks on the two protagonists, haunting, perplexing and tempting them to open up its mysteries and come to an understanding of Frank's death and their own existence.
