Lily-May, wife of Detective Murray and mother to beautiful Callie, tragically goes missing, with her daughter witnessing the ordeal, but unable to save her mother from the captor's grip. Will Callie be able to live with herself?

A mystery as to where she is or how she got there and to stay alive, Lily begins a new life pretending to be someone else. Will she ever be found, or will her captor carry out the unthinkable when he learns her true identity?

Back home, Lily's husband and daughter have been left to pick up the pieces. While both suffer immeasurable pain and emptiness, Callie believes she has seen her mother on a number of occasions but has been too scared to tell her dad who, unbeknownst to her, has witnessed his own sightings of this same woman.

Has Lily returned, or is it her ghost back to haunt her daughter and husband?
