After six seasons on NBC, "Law & Order: Criminal Intent" moves to USA network for its seventh season beginning in October. In the seventh season, Detective Robert Goren (Vincent D'Onofrio) returns to the job after a highly charged case in which he learned a serial killer on death row might have had ties to his dying mother. While Detective Goren grapples with questions of identity, Detective Alex Eames (Kathryn Erbe) confronts a ghost from her past when she's compelled to re-open the investigation of her husband's murder. Meanwhile, Detective Mike Logan (Chris Noth) gets a temporary new partner, Detective Nola Falacci (Alicia Witt). She's brilliant, forceful, and so driven that Detective Logan finds himself in the unaccustomed position as the voice of reason.
