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.

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.

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.

several months after foiling a terrorist attack on Dodger Stadium, FBI agent Darwyn Al-Sayeed is about to start a new life as a teacher at Quantico when he is asked to investigate a new terror suspect. Former cell leader Farik is interrogated by the CIA.
