Tarik and Tessa are becoming leaders in their own right. The crime world is stirring, and SIU finds themselves in the middle of a war. Then, as luck would have it, they get a key piece of information linking Jimmy's shooting to Argon. Tarik and Han go head to head in a battle of wits to find Jimmy's killer and once the dust settles, no one will be the same.

The sins of SIU have come back to haunt them. A team member has been kidnapped by a highly intelligent vigilante. The Vigilante's motives become clear and has been plotting for a long time. As the Vigilante's master plan draws to its conclusion the question becomes will SIU join him in his crusade or will they stop him?

Jimmy is up and about and staying away from SIU. Miriam and Zakia continue to work the case against Argon, but Argon and Han are plotting, and their plans are unfolding. Darius and Argon continue their 'business' partnership with Darius' daughter held as a bargaining chip. The team is falling apart, but through it all they are still SIU.
