An amnesiac is sentenced to Death Row for a murder she can't remember committing. She is given a second chance at freedom by the FBI while being recruited as part of the secret experimental unit of the FBI's unsolved crimes division. Part of the experiment is that she is implanted with the final memories of murder victims. While she pursues the leads of other peoples' memories, she is haunted by the distant echoes of her own life... a life she can't remember.
