Detective Helen Carter is back in the thick of things. It's a race against time to catch a serial killer targeting young women.

Twenty years ago, Helen's father, Detective Richard Carter, worked himself to the bone to put away a notorious serial killer. Mark Landis earned infamy as the Button Killer, known for his gruesome habit of stuffing buttons down the throats of his victims.

Now it looks like the Button Killer is back. There's a spate of killings in the city, each victim found with his trademark signature - the button . . .

Is Helen dealing with a clever copycat killer?

Or even worse, could her father have put the wrong man behind bars?

Now the killer is leaving taunting messages demanding Landis' release - or else.

All eyes are on Helen. This case will cost her dearly, she must face her own family's dark past to find the answers so desperately needed - and the truth could shatter her life forever . . .
