Tony Ossur and Marty Iniddor are two New York City Detectives whose long-time partnership is splintered as a result of a meltdown at a Christmas holiday party. The incident plunges Detective Ossur into the depths of darkness that is usually reserved for criminal aggressors. He forces his partner into a compromise that threatens both their futures. They become involved in an investigation that has them reviving relationships that should have remained in the past, and which attack the strict code of police integrity. It ultimately leads them into a head-on collision with a planned terrorist plot that has international ramifications. Tony and Marty, with the help of the other detectives in the Brooklyn South Squad, have the potential to thwart a possible rebel "take-over," but at a price that would ultimately change their lives forever
