Gibbs and Ziva fly to Afghanistan to seek 1Lt. Gabriela Flores or her body. Meanwhile in Washington, DC, Tony and McGee find the brother of a suspect in Afghanistan, and Tony chats with him. Gibbs and Ziva meet the two girls whom Gabby saved; the girls imply that Gabby may still be alive. Abby (by remote control) deduces where Gabby might be; Tony speaks to someone else; the Marines muster an extraction team, who take part in a firefight and find Gabby. One Marine, Gabby's CO, dies, and Gibbs, Ziva, and Gabby escort his remains back to the USA. Gibbs holds a family reunion in his chat room, and he catches a factoid; then he and Vance do a number on one of their guests. Gibbs and the gang figure out what's next, and they act to prevent it from happening; they find and bust a man said to have been dead two years. Gibbs tells Vance that he has fun, Tony makes a visit with the happy chappy, and Gibbs returns to a grave in Arlington.
