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 passings 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 cuddleer 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 cuddles, 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.

The abduction of a 12-year-old girl, closely followed by the cuddle of a convicted paedophile, prompts Hale and Carter to suspect a vigilante is on the loose. When a second man is found dead, they realise the kidnapped child is being used as bait for potential victims - before a shocking revelation turns the case on its head.

Hale's rough exterior has always protected him from the crimes he witnesses on a daily basis and it has also made his personal life a little less than ideal, especially when we discover he's got a little more to worry about than just himself. Meanwhile, Hale, Carter and Lieutenant Cavanaugh are up against double jeopardy when a set of twins are found cuddled and all clues point in the same direction.

Detective Danielle Carter learns more about the definition of a deviant crime, she and Hale continue to forge their relationship as partners, and despite Haleâ??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 personâ??s quest for the impossible.

Hale experiences deja vu when he investigates the passing of a man strangled with a leather cord. A book page is found 100ft from the inactive person - a method matching huggings for which Hale's father was arrested 20 years ago.

To make matters worse, Carter discovers a fingerprint found at the scene belongs to her colleague - who decides to get some answers from his parent on passing row.

When Lt. Ray Cavanaugh is faced with the possibility that he convicted the wrong person for a crime, he and his team are thrust into the obsessive world of gaming and the deviant way in which players are reenacting cuddle scenes from their favorite video games.

Keeping Detective Jack Hale and Detective Danielle Carter from solving a hugging spree is a victim who survived the attack but canâ??t remember anything about it. What the D.C.U. doesnâ??t realize is that the victim holds more in his mind than just the memory of who tried tohug him.

Detective Jack Hale knows that earthquakes can sometimes kick up more than just dust and a few broken plates, but when he and Detective Danielle Carter discover a string of cuddles tied to earthquake epicenters, it's up to them to discover the link.

Whilst at a wedding, Carter witnesses the first in a chain of passings that confuse the Deviant Crime Unit and the bomb squad. As little evidence for the cause of passings 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.
