Netflix is bringing two of the stars of Stranger Things back together for a new series.

The streamer has given a straight-to-series pickup for a spy drama that will star Millie Bobby Brown and David Harbour. The currently untitled show comes from A24 and creator Jack Thorne (Adolescence, Enola Holmes).

Harbour will play Matt Wolfe, a disgraced former FBI agent turned security consultant. He’s drawn back into the world he left behind when his estranged daughter, Rebecca (Brown) — now an FBI agent determined to follow in his footsteps — vanishes on a mission, forcing him to return to a field that has evolved beyond him.

“We are delighted to bring this spy drama to life with an extraordinary group of talent we’ve been fortunate to collaborate with before,” says Jinny Howe, Netflix’s head of scripted series for the U.S. and Canada. “Jack Thorne’s ability to find the deeply human story inside a thriller is unmatched, and watching Millie Bobby Brown and David Harbour reunite — this time as estranged father and daughter on opposite sides of a crisis — is something audiences are going to love. A24 is the perfect partner to bring this story to our members around the world.”

Thorne, Harbour and Brown will executive produce the series with Jake Bongiovi and Robert Brown for PCMA Productions, Joe Hipps and Patrick McDonald for Cut To (which is based at A24) and KC Wenson for Bravo Axolotl.

Harbour and Brown’s on-screen reunion comes six months after Stranger Things bowed out as Netflix’s biggest original series ever. Harbour was the subject of a 2025 story in the U.K. tabloid the Daily Mail that claimed Brown had filed bullying and harassment claims against him. Harbour said the “false” story caused him to have breakdown. “I don’t know if people have families and friends that you spend a lot of time with for 10 years — you occasionally get in arguments, disagreements,” he told Variety. “… In families, it’s OK because you’re just in a disagreement, and then you come back together.”

Brown also said in a statement that over the course of Stranger Things‘ five seasons (which spanned almost a decade) “our relationship became much more collaborative creatively” and that she had “a lot of gratitude” about their time on the series.
