The tenth season of NCIS picks up where season nine left off, as the NCIS team surveys the damage from the terrorist bombing. The team continues their search for Harper Dearing, for whom Gibbs invokes a "poke the bear" strategy after realizing that Dearing has nothing left to lose. The team continues to solve difficult cases including an investigation to find a missing armory worker and another to solve the murder of a Petty Officer who was shot and killed while driving a Ferrari. Despite fearlessly pushing forward in their professional lives, the NCIS team struggle with the aftermath of the bombing. Gibbs helps Abby cope with the psychological aftermath by encouraging her to connect with her recently discovered biological brother. Gibbs struggles with family dynamics himself, as he reconnects with his father's best friend, the man he was named after, and convinces his father to let go of a grudge and reunite with him.
