Su, born in prison, has always wanted to see the "crow" from the story her mother told her. On the day she was going to be secretly executed, Gill, an artificial intelligence with a database of everything outside the prison, was thrown into prison for a test run. Su develops a special feeling for Gill, not caring whether her words are programmed or self-conscious, and not trying to tell if she has human emotions. Unable to distinguish her own human feelings... in this small cell, the lonely Su got her first doll--she met a "person" who could comfort her soul.
