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.

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.

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.

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.
