Nick Jandl

The murder of a Petty Officer in a small town outside D.C. prompts NCIS to once again work with "The Sherlocks," a privately funded investigative team that includes their newest member, Anthony DiNozzo, Sr. (Robert Wagner). Richard Riehle returns as Walt Osorio, Jessica Walter returns as Judith McNight and Todd Louiso returns as Lyle Waznicki, all members of "The Sherlocks."

Casey (Jesse Spencer) and Severide (Taylor Kinney) find themselves at odds after Casey argues with him over the best way to save a teenager entangled in barbed wire. When Casey looks to Boden (Eamonn Walker) for help smoothing out the situation, he comes to the realization that he will have to fix it himself. Elsewhere, Otis (Yuri Sardarov) tries to convince Casey to participate in the beta test for an expensive piece of new firefighting equipment imported from Japan. Meanwhile, Kidd (Miranda Rae Mayo) and Hope (guest star Eloise Mumford) come to blows over a payroll issue and Brett (Kara Killmer) goes on a date with a doctor she meets during an ambo call.

Rayna promises to help Deacon battle his illness and Sadie faces her past head on.

Rayna is floored by Edgehill’s plans to sign Maddie as a solo artist.

Deacon and Rayna confront the threat to their future together, and Juliette’s spiral prompts Avery to action.
