Despite a bomb attack on Gibbs and the team, duty continues to call for these special agents as they try to regroup and put the pieces back together.

When Season 10 ended in the series' biggest cliffhanger, the NCIS was virtually disbanded and Gibbs was aiming a rifle at the FBI agent responsible.

In Season 12, Gibbs and McGee travel to Russia to retrieve a computer expert and get into an ongoing battle with mercenary Sergei Mishnev.

Following the unexpected departure of a key member, the NCIS team regroups and recruits several new faces, including a former MI6 operative.
