When a man is shot by the Secret Service outside the vice president's official residence, NCIS is aided in the case by a new member of the team: an AI chatbot being beta-tested by the Department of Justice.

On her first NCIS: Elite mission, Knight is given orders to hunt down and arrest Eleanor Bishop after the former member of the NCIS team is designated a wanted cyber-terrorist. In need of someone to trust, Bishop turns to Torres, and the two come face to face for the first time since she abruptly left nearly five years ago.
