The story follows Adrian Shields, a police detective of about forty years of age who has spent almost half of his life working. What's it like to work as a cop in Detroit when there's a catastrophic shortage of manpower, the labs are woefully under-equipped, the equipment is obsolete, and the city has zero cameras that can easily help you find a criminal and point out where he's hiding? Well, it's a hell of a job, but he did the best he could.

The main case in his career would be the investigation of a series of murders commited by a man nicknamed the "Heartbreaker".

Since 1993, the Heartbreaker has brutally murdered children between the ages of four and seven every couple of months. To begin with, he slit the throat of a child who was still alive and then cut his heart out of his chest. Despite the brazen nature of some of the murders (i.e, children being abducted straight from their homes while family members were present) no one has actually seen the Heartbreaker. Moreover, he is extremely cautious and cunning.

Up until the beginning of the plot, the police have no fingerprints or DNA of the perpetrator. Adrian has been working for several years as part of a task force that deals exclusively with the case of the Heartbreaker. Then finally there is a chance for justice to nail the perpetrator...
