In the series, inspired by Paul Warner’s debut novel ‘A Spy In the Blood,’ disgraced FBI agent turned security expert Matt Wolfe (Harbour) is 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.

Here’s what Netflix’s head of scripted series Jinny Howe had to say about the new project:
“We are delighted to bring this spy drama to life with an extraordinary group of talent we’ve been fortunate to collaborate with before. 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.”
