Darwyn Al-Sayeed 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.

Farik and Ilija receive a deadly biological anthrax shipment and prepare for an attack inside a Los Angeles shopping mall.

Farik learns that the money supply filtering in from Mexico to finance `Youmud Din Judgement Day' has come to a halt. Farik, Darwyn and Christian cross the border to Tijuana, Mexico, and attempt to straighten out their financial problems.

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

The cell members pose as insurgents in training to secure a new base of operations.

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.
