Saison 1 - NCIS : Enquêtes spéciales

The first season is composed of twenty-three actual episodes of the NCIS series and two introducing the NCIS characters in episodes 20 and 21 of season 8 of the JAG series. At the beginning of season 1, the character of Caitlin Todd, a former Secret Service agent, is invited to join the NCIS team, which will be done in episode 3. Then a 'common thread' is set up when a terrorist takes medical examiner Ducky, his assistant Gerald, and agent Kate hostage (episode 16). From then on, Leroy Jethro Gibbs will track him down until the final episode of the season in which he will discover the identity of this man: Ari Haswari. Another problem will then arise because Ari is a double agent of the Mossad, infiltrated into a terrorist cell and protected by the FBI.
