Peter Krause Is Back! NBC’s Line of Fire Teaser Has 9-1-1 Fans Ready for September

Not us still recovering from Bobby Nash being cruelly ripped away from our screens last television season, only for Peter Krause to pop back up on NBC looking like a million bucks in a tailored suit. Yes, girl, the king of procedural television is officially back. NBC dropped the first teaser trailer for its highly anticipated crime drama, Line of Fire, and it is safe to say our Monday nights are officially booked.

Originally developed under the mysterious pilot title Protection, Line of Fire is already generating massive buzz as the network’s next flagship drama. Snagging the coveted post-The Voice timeslot on Monday nights, the series is scheduled to premiere on Monday, September 21, 2026, at 10 p.m. ET/PT, with episodes streaming the next day on Peacock.

If you missed the teaser or just need a breakdown of what to expect from this high-stakes family crime thriller, we have compiled everything you need to know about your next television obsession.

The Hollingsworth Family: A Multi-Generational Law Enforcement Dynasty

The Hollingsworth family is here to make your holiday arguments look like a walk in the park. Line of Fire centers on a deeply tight-knit, multi-generational family where practically everyone holds a badge, a gun, or a high-level security clearance.

Krause leads the star-studded ensemble as Mike Hollingsworth, a veteran Secret Service agent who clearly knows his way around a tactical vest. But he isn’t the only one keeping the peace. The family tree is stacked with serious federal firepower. Hope Davis stars as Jane, Mike’s wife and a fierce U.S. Marshal. Kat Cunning plays their daughter, Clare, an elite FBI agent.

Tommy O’Brien portrays their son, Micah, following in his father’s footsteps in the Secret Service. Taylor Bloom rounds out the immediate family as Russ, a sharp analyst working for the Department of Justice (DOJ). The series also stars fan-favorite Charlie Barnett in a pivotal role.

The teaser highlights the family gathering for their traditional weekly dinner. The vibes are immaculate, until you realize they are trading stories about international fugitives and asset protection over the mashed potatoes.

Blue Bloods Meets Scandal: The Plot and The Premise

So, what is the actual story here? The official logline hooks you immediately. The central conflict ignites when a U.S. Marshal is killed in the line of duty. What initially looks like a tragic but standard operational hazard quickly unravels into a massive, deep-rooted federal conspiracy.

Suddenly, the Hollingsworths find themselves targeted by a shadowy, highly skilled assassin who seems to know their every move. To survive the onslaught, this family of protectors must turn their skills inward. Whew. They are forced to break their

own professional codes, cross legal boundaries, and rely entirely on each other to stay alive.

The industry chatter is already calling Line of Fire NBC’s direct response to CBS's long-running hits, but with a serialized, fast-paced edge. Krause himself has described the show's addictive mystery as a creative cross between Scandal and his iconic turn in Six Feet Under.

Behind the Scenes: Gossip Girl Royalty and White House Ties

The creative pedigree behind the camera is just as impressive as the faces on screen. Line of Fire is penned and executive produced by Josh Safran, the mastermind who previously brought us the addictive drama of Gossip Girl and the twist-heavy FBI thrills of Quantico. Safran knows exactly how to pace a serialized mystery, meaning viewers should prepare for massive cliffhangers every single week.

Perhaps the most fascinating tidbit about the series is its real-world inspiration. Executive producer Jenna Bush Hager leaned heavily into her own unique childhood experiences to help shape the show. Growing up as the daughter of President George W. Bush, Hager spent a significant portion of her life under the constant, watchful eye of Secret Service protection. That intimate knowledge of what it actually feels like to live inside a security bubble brings an undeniable layer of authenticity to the Hollingsworth family dynamic.

The TV Cave's Initial Verdict

Network television has been missing a glossy, high-stakes thriller that actually respects the audience's intelligence. Watching Peter Krause navigate a massive government conspiracy while trying to keep his heavily armed children from killing each other at the dinner table? Sign us up immediately.

Safran’s signature fast pacing combined with a stellar cast means Line of Fire has all the ingredients to become a massive breakout hit this fall. Mark your calendars for September 21, because this is one premier you cannot afford to miss.
