When Peter Krause said goodbye to 9-1-1 after eight seasons as Captain Bobby Nash, fans were left reeling. Now, the actor is ready to step back into the spotlight with a new NBC drama that promises to be just as intense. Line of Fire has officially set a fall 2026 release window, and the first images are here to tease what's coming.
The series, created by Josh Safran, centers on the Thornhill family—a clan of law enforcement agents who work across the FBI, US Marshals, Secret Service, and Department of Justice. Krause plays Mike Thornhill, a patriarch whose family must navigate personal conflicts while tackling high-stakes cases. According to the official logline, a seemingly routine case spirals into a deadly conspiracy, forcing the Thornhills to rely on their collective expertise—and sometimes bend the rules—to protect each other and bring a killer to justice.
The first look images offer a glimpse into the family dynamics, including tense domestic scenes and a nighttime moment on a playground that hints at the collision between their personal and professional lives. The cast includes Hope Davis, Kat Cunning, Tommy O'Brien, Taylor Bloom, and Charlie Barnett, all of whom bring depth to this ensemble drama.
For Krause, Line of Fire marks his first major TV role since his emotional exit from 9-1-1, where Bobby Nash sacrificed himself to save a colleague during a deadly virus storyline. At the time, Krause acknowledged the pain fans felt, saying, "I've heard that many fans are upset by this loss, and they have a right to be. It is a loss." He added that Bobby's arc honored real first responders who risk their lives daily. "He was willing to sacrifice himself so that others could see another day," Krause said. "And I will miss everybody dearly."
Now, Krause is building a new TV family with Line of Fire, which will air on Mondays this fall on NBC. The series is already generating buzz as a potential replacement for fans who loved Krause's previous work. For those craving more high-stakes drama, check out Netflix's 'Legends' Is the Peaky Blinders Replacement You've Been Waiting For or Bob Odenkirk's 'Lucky Hank' for a different kind of character study.
With a strong cast and a premise that blends family drama with procedural thrills, Line of Fire could be the next big hit for NBC. The fall 2026 premiere gives viewers plenty of time to catch up on Krause's past work—or simply wait for the Thornhills to take over Monday nights.
