Series star Rocky Carroll, who plays NCIS Director Leon Vance, also directed the new episode "Pledge of Allegiance," which finds the team investigating the case against Navy Chief Warrant Officer Rafi Nazar (guest star Artur Zai Benson), who is suspected of trying to sell stolen classified Navy software. The tech in question, which is used to pilot combat drones, could have devastating consequences if it fell into the wrong hands. Amanda Schull and Denise Crosby also guest star.
