Police officer Mikie Fitzpatrick spent years patrolling Philadelphia's 24th Ward. She knows almost all the prostitutes here by name. She is familiar with the color, taste and smell of complete hopelessness. She knows what lengths people go to for a dose. She found bodies of people who died from dope on the streets; every year their number only increased. And every time, arriving at a call and seeing a cold, numb body, Miki prayed: “Just not Casey, at least not Casey!” Not her sister, who has long since gone downhill and is selling herself for a dose... Especially now that a serial killer has taken to the streets of the area, hunting people like Casey. Miki is at odds with her sister - but she has been accustomed to taking care of her since childhood. And she understands: Casey needs to be saved right now. Or never again...
