In Season 13 of the hit series NCIS, the missions turn personal when a hostage situation traps one of their own, new evidence calls the unit's conclusions into question, and a threat from the past targets the team and their allies. Yet even when the danger hits close to home, Special Agent Jethro Gibbs (Mark Harmon) knows he can count on his supremely skilled team to cope with the crises that affect U.S. military personnel and national security. As the stakes rise higher than ever, Special Agent Anthony DiNozzo (Michael Weatherly) makes his final exit in the unforgettable conclusion. Pauley Perrette, Sean Murray, Brian Dietzen, Emily Wickersham, Rocky Carroll, and David McCallum co-star in the 24 thrilling episodes collected on DVD for the first time in this 6-disc set.
