Line of Fire Premiere Reveals Krause's 'Dead' Son Is Alive

The NBC debut ended by revealing Charlie Barnett's Jack, said to have died years earlier, is alive and killing people watching the Hollingsworths.

NBC's 'Line of Fire,' starring Peter Krause and Hope Davis as Secret Service agent Mike Hollingsworth and U.S. Marshal Jane Hollingsworth, premiered Monday, September 21 at 10 p.m. ET/PT, introducing their law-enforcement family: FBI agent Clare (Kat Cunning), Secret Service agent Micah (Tommy O'Brien) and DOJ analyst Russ (Taylor Bloom). According to Us Weekly, the premiere closed with a twist: Jack (Charlie Barnett), Mike's son from a first marriage who had been described as having died years earlier, is alive, hiding in plain sight — and he killed someone who was spying on his family.

For devoted fans of broadcast family dramas, the moment lands as a genuine reversal: a character written off before the series even began, mentioned only in passing as dead, turns out to be the season's central mystery. Hope Davis told Us Weekly the questions — is Jack alive, what is he doing, who is murdering federal agents, and is he involved — will play out across the entire season, and that the cast themselves do not know all the answers yet. TV Guide's reviewer says they gasped at the end of the pilot episode, calling the initial twists genuinely effective despite some heavily telegraphed plot beats.

The show was created by Joshua Safran ('Gossip Girl,' 'Quantico') and executive produced by former First Daughter Jenna Bush Hager. The Hollywood Reporter's interview with Krause describes a household of five federal agents whose jobs force them to lie to and keep secrets from one another. Hope Davis tells Us Weekly that Jack went undercover and never came back, and that it 'ripped the family apart' — a source of incredible pain for the parents. Davis also credits Safran's story architecture, and Krause says he asked the creator not to tell the actors things their characters would not know, so the cast experiences blind spots the way the audience does.

The premiere arrives 17 months after Krause's beloved '9-1-1' fire captain Bobby Nash was killed off on April 17, 2025, after eight seasons — a death that, as Krause tells USA TODAY, left 'a lot of upset fans.' He tells The Hollywood Reporter he was not planning to jump back into a long-running series, but signed on because of Safran's script, its humor and its family element. Krause also reflects on his decades in television, from Carol & Company through Sports Night, Six Feet Under and Parenthood, telling THR that he is drawn to characters 'trying to answer to their moral compass.'

USA TODAY reports that Bush Hager connected the production with Secret Service consultant Steve Hughes, a 25-year agency veteran who served on the presidential details of George W. Bush and Bill Clinton, and who signed off on a set modeled after the Eisenhower Executive Office Building. Per USA TODAY, Krause learned Bush was 'incredibly punctual,' and the show teaches Krause how to exit presidential vehicles correctly. The Hollywood Reporter adds that Chris Chalk plays the president and Sam Waterston the former president. Krause tells USA TODAY the show deliberately avoids real politics: 'this is not the same reality.'

'Line of Fire' airs Mondays at 10 p.m. ET on NBC, with new episodes streaming the next day on Peacock. Us Weekly reports the series was still in production on its first season when the premiere aired, with the actors filming episode seven by Krause's count in The Hollywood Reporter interview. Davis teases that the Jack mystery will unfold across the whole season, while Krause says the characters — like anyone — have blind spots. For a network betting its fall on a broadcast throwback, the premiere's gasp-ending gives 'Line of Fire' exactly the next-morning moment the genre lives on.
