Nora and Saul's not-so-loving mother Ida makes an unwelcome visit to celebrate a milestone in her daughter's life.

The CSI team race against time to find and deactivate a radioactive bomb that has been set to go off in the middle of downtown Miami to cause destruction and terror.

Darwyn struggles not only with his new position as leader of the cell, but also with his new FBI Case Agent, Warren Russell, whose lack of experience may make him more of a hindrance than a help.

The Cell kidnaps a chemical truck driver and his rig in preparation for Youmud Din (Judgement Day). Meanwhile, Serxner and the FBI prepare to stop the attack in all three cities. Farik gives the jihadis one last night to themselves as he meets and bids farewell to his own wife. The Cell learns that the target is Dodger Stadium and the attack will be happening one day earlier than the FBI previously believed.

When Darwyn discovers that the explosion is a decoy, he leaves a clue he hopes will lead the FBI to the true target.

Following the recent tragedies, Darwyn struggles with his guilt and decides to confront Farik.
