Last night, CBS released the new promo/spoiler clip (below) for their upcoming "NCIS" episode 21 of season 11, and it appears that things will get extremely emotional and drama-filled as a young lady seems quite distraught over her recent assault tragedy, and more. The episode is titled, "Alleged." In the new episode 21,a Navy officer is going to be found dead on a rural road, causing the NCIS team to ascertain if the murder was the result of a bar fight or because he knew too much about an attack on a fellow female officer. In the meantime, Dinozzo and McGee will start up a cleanse to purge their bodies of toxins. The episode was written by Scott Williams, and it was directed by Arvin Brown. Episode 21 is scheduled to air on Tuesday night, April 15th at 7pm central time on CBS.
