Blaming herself for what happened, she becomes a stone-cold cop who fears nothing to prevent others from living through a similar tragedy. But six years later, on the very same day the killer is finally set free, she finds a chilling letter in her mailbox threatening to once again steal what's most important to her. And though she wants nothing more than to make him pay for her sister's life that he stole, she'll have to watch her back now that there's a killer on the loose.
