Detective Jack Hale took a hiatus from the force when his partner died in the line of duty. Now back at work for the San Francisco Police Department’s Deviant Crime Unit, Hale is taking on the bizarre and deviant crimes committed by San Francisco’s most aberrant criminals. In his latest case, Hale tries to find an answer for the inexplicable deaths of healthy young women who seem to have died in their sleep. The investigation leads the detective to the lab of a local professor and a realization that makes everyone’s skin crawl.
Detective Jack Hale meets his “real” partner, Detective Danielle Carter, after learning Lyford was a plant by Lt. Cavanaugh to ensure he was ready to return to the toughest unit of the S.F.P.D. While Hale is getting to know and trust his new rookie partner, he and Carter must contend with a murderer who seems to be taking back the life-saving gifts from organ donor recipients. Not only are they in a race against time to stop this bizarre pattern of murders, but they also are beginning to realize that the motives for a crime can expose the monsters that may lurk just beneath the surface of all of us.
Detective Danielle Carter learns more about the definition of a deviant crime, she and Hale continue to forge their relationship as partners, and despite Hale’s best efforts, he is beginning to warm to her. Meanwhile, Hale and Carter are thrust into the dark underworld of Egyptian mythology as bizarre crimes involving ancient hieroglyphs and rituals have the D.C.U. on a hunt for one person’s quest for the impossible.
Jack Hale is reminded of a past he had hoped to forget when a copy-cat murderer forces him to reconnect with the one man he hoped never to see again. Meanwhile, Detective Carter and Lieutenant Cavanaugh are torn between their desire to protect Hale from his demons and letting those demons fuel his determination.
Whilst at a wedding, Carter witnesses the first in a chain of deaths that confuse the Deviant Crime Unit and the bomb squad. As little evidence for the cause of deaths is left at the scenes of the crimes, both departments are stuck for answers. There is a twist when Jack and Carter soon discover that everything was not as it originally seemed.
