The gauntlet has been dropped, and Lucy has no choice but to play a sadistic killer's game. Unable to trust anyone, Lucy scrambles to find the truth. But time runs out, and she must do the one thing she swore she'd never do: tell the truth about the people she's killed. Will Lucy's ultimate sacrifice be enough?
