Sam and Bailey work with FBI field agent Susan Marsh whom is tracking Robert Lee Gregg, a conservative civic leader in Atlanta whom is suspected in the killing of six gay men. But their investigation is happened by Susan's former boyfriend, Richard Russell, whom is stalking her. Susan insists she's in control of the situation, but Bailey thinks otherwise when her boyfriend is found murdered and Russell is a suspect. Things get worse when Russell targets Bailey and his ex-wife Janet whom are now back together. Meanwhile, Sam leaves the investigation and travels to Miami to investigate the disappearance of a local man who may be connected to the Gregg killings, and she finds herself being perused by Mario Monagno (from the 'Heads, You Lose' episode) whom still wants to date her.
