Judgement Day has arrived and Fariq isn't yet out of surprises. A surprise diversion proves effective in allowing the cell to escape their surveilance. A quick thinking Darwyn leaves a clue that will hopefully lead the FBI to the target location in time.

When an Afghan boy arrives at the warehouse looking for training as a jihadi, Darwyn introduces him to a more moderate brand of Islam in hopes of steering him away from terrorism.

The cell buys explosives from a white supremacist militia while Darwyn's new handler, Patrice Serxner, tries to prevent the LAPD from blowing his cover in a conflicting investigation.

The cell hijacks a chemical truck in preparation for Judgment Day, as Farik spends a last night with and bids farewell to his wife, and the FBI prepares to stop the attack.

Farik dispatches a biochemical student on a flight to Vancouver, Canada, to drive a shipment of real anthrax across the Canadian border and down to Los Angeles.

Farik and Ilija receive a deadly biological anthrax shipment and prepare for an attack inside a Los Angeles shopping mall. Darwyn's supervisor Ray Fuller become suspicious about the disappearance of a cell member.

Farik, Darwyn and Christian cross the U.S.-Mexico border at Tijuana to find out why the cell's pipeline of mob funds has suddenly gone dry.

The cell members pose as Iraqi insurgents-in-training in order to infiltrate and take over a secure warehouse as a new base of operations for Youmud Din ("Judgment Day").

Darwyn befriends a pesticide plant worker in order to buy some of his company's product under the table for the cell, while each of the jihadis cope with personal troubles of their own.

Darwyn Al-Hakim is a Muslim ex-con who has just been released from prison and finds his way to an Islamic extremist named Farik, who recruits him to join a terrorist sleeper cell planning an attack in Los Angeles.
