Years later, when a series of gruesome displays of murder appear throughout the city, the past and present collide as Harley’s obsession with finding the depraved psychopath responsible leads her down a dangerous path. She must decide how far she is willing to go, and what lines she is willing to cross, to solve these cases once and for all.
