Line of Fire Premieres Tonight on NBC: Peter Krause Leads New Family Crime Drama
NBC is putting its newest crime drama Line of Fire in the spotlight as the series makes its television debut Monday, September 21, 2026.
The new drama stars Peter Krause and Hope Davis as members of a family whose professional lives are deeply connected to federal law enforcement. The series premieres at 10 p.m. ET/PT on NBC and will be available to stream the following day on Peacock.
The premiere is the immediate reason “Line of Fire” is drawing attention in Google Trends. Unlike an older title or catalog search, the keyword is tied to the launch of a brand-new network series tonight.
What Is Line of Fire About?
Line of Fire follows the Hollingsworth family, whose members work across agencies including the FBI, U.S. Marshals, Secret Service and Department of Justice.
The family’s professional expertise becomes especially important after what initially appears to be a straightforward case develops into a deadly conspiracy. The characters must work together while dealing with the personal tensions inside their own family.
NBC describes the central conflict as a situation in which the family must protect one another while pursuing a killer, even when doing so could force them to cross professional boundaries.
Peter Krause Returns to Network TV
Krause plays Mike Hollingsworth, a Secret Service agent and one of the central figures in the family.
The role marks a return to network television for Krause following his departure from 9-1-1. His casting has been one of the major talking points surrounding the new series, particularly because Line of Fire also places him in another first-responder-oriented drama.
Hope Davis plays Jane Hollingsworth, Mike’s wife and a U.S. Marshal. Their relationship is part of the show’s family storyline, alongside the professional responsibilities shared by their children.

The main cast includes:
- Peter Krause as Mike Hollingsworth

Why Is Line of Fire Trending Now?
The timing is straightforward: Line of Fire is making its network debut today.
NBC began promoting the series ahead of its fall launch, including the release of a trailer in August that introduced the Hollingsworth family and the show’s central law-enforcement storyline.
Interest has also been helped by Krause’s return to television and the unusual setup of a family whose members work for different federal agencies.
