NBC’s upcoming drama Line of Fire is taking a familiar television formula crime, federal agents and a dangerous conspiracy and giving it a more personal edge. Instead of focusing only on the investigation, the new series places an entire family of law-enforcement professionals at the center of the danger.
The official trailer, released by NBC ahead of the fall 2026 season, introduces a family whose professional lives span the FBI, U.S. Marshals, Secret Service and Department of Justice. When a case that initially appears straightforward develops into something far more sinister, their careers suddenly become inseparable from their personal survival.
At the heart of the series is Peter Krause, who plays Mike Hollingsworth, a Secret Service officer and member of this unusually complicated family. Hope Davis co-stars as Jane Hollingsworth, while Kat Cunning, Tommy O’Brien, Taylor Bloom and Charlie Barnett round out the principal ensemble.
A Crime Thriller Where Family Is the Weakness and the Strength
What immediately separates Line of Fire from a standard procedural is the relationship between its central characters.
These aren’t colleagues who meet because of one case. They are relatives whose professional expertise has shape by years of protecting other people. That creates an intriguing dramatic contradiction: the people most capable of solving a dangerous case may also be the people with the most to lose.
According to the series premise, a seemingly cut-and-dry case becomes a deadly conspiracy, forcing the Hollingsworth family to combine their specialized knowledge to uncover the truth and protect one another. The situation may ultimately require them to cross professional boundaries and even compromise the codes they have sworn to uphold.
That gives the trailer a more layered hook than simply asking, “Who committed the crime?” The bigger question is how far these characters will go when the investigation becomes personal.
Peter Krause Takes Center Stage
For viewers familiar with Peter Krause’s television work, Line of Fire represents an interesting new chapter.
Krause has built a career around characters who can balance authority with emotional vulnerability, and that combination should fit naturally into a story where professional responsibility constantly collides with family loyalty. His character, Mike Hollingsworth, is not simply another federal agent at the center of an investigation. He is also the patriarch of a family whose members are individually connect to the machinery of federal law enforcement.
The role also marks Krause’s return to network television following his long-running role as Bobby Nash on 9-1-1. Speaking about the new series, Krause described it as a combination of suspense, action-thriller storytelling, crime solving and family dynamics.
That mixture could become one of Line of Fire‘s biggest advantages.
Joshua Safran Brings the Conspiracy Together
The series comes from Joshua Safran, who serves as creator, showrunner, writer and executive producer. His previous television work includes Gossip Girl and Quantico, making the combination of personal relationships, secrets and high-stakes institutional drama particularly relevant to his television background.
Safran is joine by executive producers Jenna Bush Hager and Ben Spector, with Rebecca Thomas directing and executive producing the pilot. The series is produce by Universal Television, part of Universal Studio Group.
The creative setup suggests that Line of Fire is designed to operate on two levels: as an accessible crime drama and as a continuing family mystery.
What the Trailer Suggests About Season 1
The trailer doesn’t simply sell Line of Fire as another federal-agency procedural. Its strongest selling point is the collision between duty and loyalty.
The Hollingsworth family has spent their lives protecting civilians and public officials. Now they appear to be facing an enemy capable of turning that expertise against them. A mysterious assassin, a deadly conspiracy and disagreements inside the family create a story where knowing how to protect someone may not be enough.
That could allow the series to move beyond individual weekly cases and develop a larger mystery throughout Season 1.
The visual tone also emphasizes the contrast between professional control and personal uncertainty. Characters accustomed to operating under pressure are suddenly dealing with threats that cannot be separated from their relationships.
Line of Fire Season 1 Release Date
Line of Fire premieres Monday, September 21, 2026, at 10 p.m. ET/PT on NBC. New episodes are scheduled to stream the following day on Peacock.
The September launch places the series firmly within NBC’s 2026–27 television lineup, giving the network a new dramatic property built around an established television lead and a broad law-enforcement premise.
Final Thoughts
The Line of Fire Season 1 trailer makes a convincing case for a crime thriller that wants its emotional stakes to matter as much as its mystery. The federal agencies, assassins and conspiracy provide the surface-level suspense, but the family relationship is potentially where the series could distinguish itself.
Peter Krause gives the project an experienced dramatic lead, while Joshua Safran’s involvement points toward a story driven by secrets, relationships and escalating complications. If the series can successfully balance its procedural elements with the Hollingsworth family’s internal conflicts, Line of Fire could become one of NBC’s more intriguing new dramas of fall 2026.
For viewers looking for a new NBC crime thriller in 2026, a Peter Krause drama, or a series combining family tension with federal investigations, Line of Fire is certainly worth keeping on the radar.
