Tonight at 10 p.m. ET/PT, NBC would like to reintroduce you to Peter Krause, a man television has been putting through it. After 9-1-1 killed off Bobby Nash and left an entire fandom in group-chat mourning, Krause is back — in a suit, with an earpiece.

In Line of Fire he plays Mike Hollingsworth, a Secret Service agent staring down a retirement he did not ask for. He is not processing this quietly, because his entire family is also federal law enforcement.

One family, four agencies, zero boundaries

The Hollingsworths are a jurisdictional fever dream: Krause's Secret Service patriarch, Hope Davis as a U.S. Marshal matriarch, an FBI daughter, another Secret Service son — Thanksgiving at this house must require interagency clearance. The hook: a case curdles into a conspiracy, a trained killer starts circling the family, and suddenly everyone's professional code is more of a professional suggestion.

The show comes from Joshua Safran (Quantico, the Gossip Girl reboot), and the receipts-holder in the producer credits is Jenna Bush Hager — a woman who literally grew up inside a Secret Service detail and is now monetizing the trauma, which I respect enormously. Sam Waterston drops by as the President, because of course he does.

Krause, on the record

He's not pretending the 9-1-1 exit didn't sting. As he put it: "It was hard. I loved Bobby Nash and the audience did too."

"There's still room for great storytelling on network TV."

A romantic! What sold him on this one was the blend — family mess plus central mystery plus criminal case — and the friction between Mike and Davis's Jane: "There's a lot of emotional energy between Mike and Jane, I look forward to that extended storyline." Married Marshals-and-Secret-Service energy, if you will.

What to expect, practically speaking:

  • Tonight, 10 p.m. ET/PT on NBC, streaming next day on Peacock
  • A serialized conspiracy wrapped in a weekly-case shell
  • Krause and Davis doing seasoned-actor jujitsu on network-drama dialogue
  • At least one dinner scene that doubles as an interrogation
