Giuseppe “Discipline” Cain is a cold-hearted, calculated, and resentful murderer who turns Philadelphia into his own personal killing ground. As the death toll rises, city officials and the police department clamor to calm the fears of the citizens about this brazen serial killer. When an elected official’s family member is found dead, no one in the city is safe.

Detective Aaden Bravo is a highly decorated officer with a legendary clearance rate. Detective Christian Bennett is flashy, reckless, and a serial womanizer. After Christian’s transfer to the Philadelphia Police Department’s homicide division, these two starkly contrasting officers are forced to work together. Despite their disdain for each other, Aaden and Christian’s skill sets complement each other. While Aaden is all about the job and Christian is all about the women, their next case is all about survival.

Will they succumb to the pressure of maintaining their partnership, or can they cast aside their differences and stay alive long enough to bring Discipline to justice?
