The detectives put their private problems on hold as Mason calls for "all hands on deck" to investigate the murder of Dawn Cofield, a college co-ed. Pup Clemmons, the co-ed's boyfriend and Stone's rival from his undercover days, resurfaces as one of the possible suspects. But it's a crowded field that also includes Alex Caldwell, Pup's competition for the crime turf; a Pakistani drug runner from Canada; one of Dawn's professors who has the reputation of a Lothario, and a preppy classmate from a politically connected family. Meanwhile, Sanchez tries to find out the truth about Stone's junkie ex-girlfriend, Riley Sullivan, who is still hanging around the squad and trying to reignite her relationship with Stone. Is this as sincere attempt to get her life back together, or is she playing him? Then, a tense standoff results in a cataclysmic event.
