Brothers in Arms

Director Shepard meets an informant named Troy Webster who has information on international arms dealer La Grenouille but Webster is killed during a gunfight, prompting Gibbs and his team to take charge of the investigation. Shepard later becomes convinced that La Grenouille, the arms dealer she has been chasing down is the one who ordered the kill but the team are all doubting her judgement, believing she might be on a personal revenge trip which is further increased when she manages to lead the team into a trap, leaving them with no clues to La Grenouille's whereabouts even after days of investigations.
