A young woman works as a waitress in a diner. Her relationship with her boyfriend is unfulfilling and to further complicate things she is obsessed with a large hemangioma, or benign vascular tumor, on her hip (one that we actually never see). One day after she encounters a mysterious man wearing a hood and playing a clarinet she discover a small shack built out of cardboard. She crawls into it and suddenly we are transported to this young woman's interior world, a place where she meets her own doppelgänger in the form of a large doll who bears the same birthmark on her hip.
