Sugar (2008)

Sugar tells the story of Lyle Tate, an ordinary man viciously attacked in his own home by a mysterious masked intruder. He is left with physical scars and develops acute agoraphobia - a fear of the outside. Cocooned in his own little world, Lyle survives through strict repetition in the mundane enclosure of his home. However, when his shopping delivery arrives with the wrong kind of sugar, Lyle is soon forced to overcome his past fears and face his worst enemy... himself. Unable to escape the shackles of his paranoia, it is only through the kindness of a stranger that Lyle finds the power to move beyond the walls of his self-styled prison.
