A serial killer stalks the streets of Atlanta. Dubbed the Weekend Killer, the murderer takes his victims on Friday and sends a souvenir to the Atlanta Major Crimes Division of the Atlanta Police Department by Saturday morning. A body part arrives on Sunday followed by a typewritten note Monday morning outlining where the body may be found. All clearly intended to provoke the police-down to the fingerprints the killer doesn't bother to wipe-and can't be traced-and right up to the moment when Mia's new stepsister and Chief Maxwell's daughter Mindy is the next victim.Mia thinks she knows things that the police don't.Should she stay out of it and let the police do their job? Should she trust her instincts and go on alone? The clock is ticking down and only one thing is for sure: one way or the other, come Monday morning, unless someone does something, Mindy is dead.
