When Selah Morse sees a young woman get hit by a speeding taxicab, he rushes her to the hospital. The girl has lost her memory; she is delirious and has no identification, so Selah poses as her boyfriend. She is released into his care, but the doctor charges him to keep her awake, and to help her remember her past. Through the long night, he tells her stories, inventing and inventing, trying to get closer to what might be true, and hoping she will recognize herself in one of his tales.
