Keira Lynch may be a lawyer, but that doesn't mean she plays by the rules.

She has been summoned to give evidence against an Albanian hit man. She was there the night he murdered the mother of a five-year-old boy. She remembers it well - it was the same night he put three bullets in her chest and left her for dead.

But there are powerful people who want the hit man back on the streets. When they kidnap the boy, she is given a choice: commit perjury, blow the trial and allow the killer to walk or give evidence, convict him and watch the child die. Keira must make a decision. This time, does she have to cross a line to win?
