As the team hunts an UnSub who severs spinal cords, they uncover a clue from their last case that points to a serial killing network. To figure out how big this network is, Rossi has to convince a reluctant Garcia to do the one thing she doesn’t want: come back to the BAU.

At the heart of the serial killing network is Elias Voit. Dangerous psychopath. Manipulative narcissist. Loving father and husband. In order to find him, the team must find all of his kill kits. But one is missing, and the path leads to a bomb in the middle of Washington, D.C.

The explosion looks to have exposed the true mastermind behind Sicarius, but all is not what it seems. Is someone taking the fall for these deadly actions? The BAU is determined to seek the truth.

Rossi will go to any lengths to prove that Elias Voit is Sicarius. But Voit turns Rossi into his own worst enemy, putting his future at the BAU in jeopardy.

With Rossi in Voit’s clutches, he grapples with the limits of his technical know-how and mental strength. As the BAU tightens their grip on Voit, he reveals just how far he’s willing to take his deadly crusade.
