Enquanto a equipe caça um criminoso que corta a medula espinhal das vítimas, eles descobrem uma pista de seu último caso que aponta para uma rede de assassinos em série. Para descobrir o tamanho dessa rede, Rossi precisa convencer uma relutante Garcia a fazer a única coisa que ela não quer: voltar para a 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 BAU hunts for the next connection to the serial killer network when they pursue a home invasion team. Alvez and Garcia convince Tyler Green to submit a cognitive interview to unlock his memories of Sicarius.

A surprising connection forces Deputy Director Bailey to ask the BAU to take a case involving young D.C. socialites who are bitten by a sadistic UnSub. But when the case turns political, the BAU finds themselves in the crosshairs from a high-powered senator. The team is led to a second shipping container that’s rigged to blow.

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.

With the fate of the Sicarius investigation hanging in the balance, the BAU takes a case in West Virginia, where an UnSub practices his own twisted form of Old Testament vengeance.

Voit’s internal struggles with himself lead him to a desperate kidnapping. But Rossi’s obsession brings the BAU closer to the truth than they’ve ever been.

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.
