Left for dead after a vicious attack, Homicide Detective Anna Walker awakes in the hospital to find she has full-blown amnesia and no recollection of her previous life. As she struggles to put the pieces of her past together, it is quickly discovered that she was a callous and competitive cop; the kind of woman who put her job above her husband and teenage daughter without hesitation and the kind of woman who was having a torrid affair with her partner. These harsh revelations lead Anna on a journey to put her life back together, make amends, and become the woman she wants to be, not who she once was. As she slowly recovers her detective skills, more details from her past trickle in, and Anna discovers that her road to recovery has not only put her life in danger, but has also threatened the safety of her family. Not knowing whom to trust, she must find out who is pursuing her, before they hurt her family and eliminate her once and for all.
