David Preston is a middle-aged lawyer, if not content, then accepting of the status quo. He has reached the height of his career, is married to a devoted woman, and he has close friends. Although he appears to have it all, a deep depression grips him. He spends time staring aimlessly out his office window at the cold, unwelcoming city passing beyond his office every day, lost in the monotony and cold anonymity. That is until one morning with his eyes fixed on the street below he sees a woman who, in a momentary glimpse, changes his life and how he views the world forever. We follow David on an erotic spiral of obsession and zealous devotion as he envisions a new life, a happier one, with this woman. What begins as simple attraction soon grows into something more, something relentless that drives him beyond the edge of madness.
