Van and Deaq go undercover to get inside the organization of one a gang boss, Cyrus One, who has been hiring assassins to gun down LAPD’s finest. They are forced to prove their worthiness by completing a couple of tasks that coincide with their specialties. Also, Internal Affairs has now assigned a new agent to oversee the workings of The Candy Store and he’s not thrilled with the cavalier attitude that the three of them have shown in the past.

Billie has been implicated in the death of Cyrus One and been taken into custody after a SWAT team, under Roland Hill’s orders, busts into The Candy Store. Van and Deaq have been suspended and now must find the real killer and take down the new leader of the organization with no help from LAPD. Meanwhile, Billie must try to stay alive in prison with the same people she helped put away.

A methamphetamine ring has been going on for some time and Van and Deaq are sent in to try and end its distribution. Billie splits them up. Van tries to get close to the distributor, a porn producer, and Deaq infiltrates the manufacturers, two adrenaline junky brothers. Things start to go bad when they have to bring in someone to mark the meth and she gets caught.

Now that Van has gotten the antidote, the caller, Nick McKussick – a former criminal and the first person that Billie trained for The Candy Store before he turned on her, has informed the group that other families have been poisoned and that their participation in his plan is not yet over. Nick orders them to help him steal an incredible amount of precious valuables or the families he poisoned will die.
