🔍The Iris Affair (2025): Cast, Plot, Release Date, Review & Where to Watch – Neil Cross Delivers a Chilling New Thriller

Sky Atlantic is bringing us another nail-biting thriller this fall — The Iris Affair, premiering 16 October 2025. Created by Neil Cross, the brilliant mind behind Luther, this upcoming series promises espionage, deception, and an intellectual cat-and-mouse game that could unravel far more than anyone expects.

At the center of this British thriller stands Niamh Algar as Iris Nixon — a rootless genius who steals a mysterious code from a wealthy, enigmatic philanthropist, Cameron Beck (played by Tom Hollander). But what begins as a theft spirals into a high-stakes pursuit, where the code may hold secrets that reshape the balance of power.

As Iris herself might warn: “It’s not just a code… it’s a key. And keys always open doors.”

🌀 The Premise

The story follows Iris Nixon, a gifted but unpredictable woman who vanishes after stealing an encrypted code. Cameron Beck, a man of influence and charm, is more than just her target — he’s someone with secrets of his own.

What follows is a tense countdown of deception, double-crosses, and mind games, as Iris races against time to unlock the code’s meaning before powerful forces close in.

The show blends mystery and thriller elements, creating an atmosphere where every glance, every silence, and every betrayal matters.
