Valentine's Day, and a dispute between rival gangs escalates into bloody violence. One teenage girl dead is left dead, another injured, and a police officer is

caught in the crossfire. Detective Inspector Charlie Resnick, nearing retirement, is hauled back to the front line to help deal with the fallout. But when the

dead girl's father seeks to lay the blame on DI Lynn Kellogg, his colleague and partner, Resnick finds the line between personal and professional dangerously

blurred.
