Episodes

Introductory episodes

The program and its characters are introduced during the eighth season of JAG. The JAG episodes, "Ice Queen" and "Meltdown", served as pilot episodes for the show. The character Special Agent Vivian Blackadder (Robyn Lively) does not appear in the series because producer Donald Bellisario felt that "she was a little soft for this kind of role".^[2] In October 2003, the two episodes were edited together and aired as "Navy NCIS: The Beginning".^[3]

The NCIS team is called in to investigate the mysterious death of a JAG officer, Lieutenant Loren Singer, when a young Boy Scout looking for his stray arrow discovers her body. As a result, a full murder investigation is opened and the NCIS team are tasked with finding a suspect for Lt. Singer's murder while interviewing her former JAG colleagues. The episode ends with Harmon Rabb being read his rights before Special Agent Leroy Jethro Gibbs officially declares him to be the main suspect in the case and as such, Rabb is arrested by NCIS for Lt. Singer's murder.

Harmon Rabb is court-martialed for the murder of Lieutenant Singer and he does not appear to have an alibi which means that if he is not proven innocent, he could end up in the brig for life. Soon Special Agent DiNozzo realizes the case is too perfect and starts searching for another possible suspect, one who might have a long-standing grudge against Rabb. Meanwhile, Gibbs tries to get information from Amad Bin Atwa, a terrorist, before there is another attack on an American ship.
