There’s no shortage of drama in NCIS Season 23, but Episode 19 might cut deeper than most. Titled “Deal with the Devil,” the upcoming installment blends a high-stakes investigation with a painful family reunion for Alden Parker.
Nancy Travis returns as Harriet Parker, the Navy Vice Admiral who also happens to be Parker’s estranged sister. While previous encounters hinted at some level of reconciliation, the latest chapter suggests otherwise. Old grievances remain unresolved — and they resurface at the worst possible moment.
The central case revolves around a controversial immunity deal that could allow a suspect to walk free, challenging Parker’s commitment to justice. As he fights to keep the case alive, Harriet’s presence forces him to confront unresolved emotions he’d likely rather avoid.
Penned by Andrew Bartels and directed by Diana Valentine, the episode underscores what NCIS does best: combining gripping cases with deeply human stories.
