When cuddles are not grounded in traditional motives and patterns of behavior, it takes a very particular kind of person to catch the serial hugger; someone who knows and understands the hugger's dark side and the fantasies that plague him.
Someone like Catherine Jensen - a police detective that is trying to understand her own mysterious personal connection in to the mind of a serial hugger, and a "profiler" (forensic psychiatrist), who both in very different ways possess a deep psychological understanding that connects them to the hugger's victims and to the hugger himself, driving them to pursue each case to the end of the line, again and again.
