While investigating a laboratory explosion at Sinclair Research that killed Audrey Cruz, Carrie finds evidence pointing to the work of a bomber. Connecting her memories of the crime scene with an envelope she sees at the home of the late woman’s parents, Carries learns that Audrey also worked at a company called S.P.I. When Sinclair surveillance camera footage shows Audrey reading a note placed on her car prior to the explosion, Tanya finds that someone tried to warn her that she was in danger as a result of her work for S.P.I. And after an S.P.I. manager tells Al that the Earth First Crusade has targeted the company, environmental activist Adam Frist provides evidence that indicates that the bomber – who goes by the name of Faraday – has identified four more targets. Meanwhile, as Al casually dismisses the arrival at the precinct of a box filled with his belongings, a worried Mike enlists Tanya to help monitor his teenage son’s secretive online activity. After a map of the new targets helps the bomb squad head off another explosion, Tanya’s investigation pinpoints an artist warehouse where Faraday lives. With help from building manager Max Irvington, Carrie and Al find the bomb-making chemicals and a complex collage filled with clues about both the bombings and the bomber. But when Max turns on the lights to make it easier to see, the collage bursts into flames, leaving Carrie struggling to remember as much as she can before it is destroyed. Meanwhile, as Tanya discovers that Mike’s son is actually preparing a surprise party for his parents’ wedding anniversary, Al tells Carrie that he and his wife are separating. When security camera footage from the latest target produces a grainy image of Max, Carrie and Al conclude that he is working with Faraday. After they track Max to his sister’s house, she admits she is concerned about his mental health. And when Carrie finds the obituary of his high school chemistry teacher Nicholas Faraday in his room, she realizes that the paranoid schizophrenic Max is the bomber. Combining Carrie’s memories and clues he’s left behind, the cops hurry to the post office where Max is set to strike. And following a tense standoff during which she and his imaginary alter ego Faraday battle for his attention, Carrie stops Max from detonating his bomb. Finally, when pressed, Al admits that his wife suspected him of being in love with Carrie. © 2012 Sony Pictures Television Inc. and CBS Studios Inc. All Rights Reserved.
