The Iris Affair (2025 TV Series) Synopsis
Created by Neil Cross, the mind behind Luther, The Iris Affair is Sky Atlantic’s newest original series — a tense and stylish thriller that fuses espionage, technology, and raw emotion. The story centers on Iris Nixon (Niamh Algar), a brilliant cryptographer who steals a mysterious activation code from visionary entrepreneur Cameron Beck (Tom Hollander) and disappears across Europe. That code holds the key to a machine powerful enough to change the course of humanity — and every government, hacker, and private syndicate wants it.
As Iris races through Sardinia, Rome, and beyond to uncover the truth behind the code, Cameron launches an international manhunt to bring her in. What begins as a chase soon becomes a psychological duel between two extraordinary minds — one fighting for control, the other for redemption.
Written by Neil Cross alongside Susan E. Connolly and Ian Scott McCullough, The Iris Affair explores the thin line between brilliance and obsession, asking how far someone will go when knowledge itself becomes the most dangerous weapon on earth.
