Two people consumed by grief.
One seeks salvation.
The other, revenge.
DI Carrie Tyler has been on desk duty since she killed her husband two years ago. When tragedy strikes again, Carrie must take the lead on what appear to be drug-related gang killings.

Time's running out before the third murder. Carrie and her team are in a race against the clock to find out whose daughter died, who killed her, and more importantly...
Who's handing out the receipts?
