The stakes have never been higher as Slow Horses: Season 5 hits Apple TV+ on September 24, 2025. After the explosive events of Spook Street, the agents of Slough House are once again pulled into the shadowy world of espionageβwhere trust is scarce, and every move could be fatal. This season kicks off with a double episode premiere, launching a tightly wound six-episode arc full of twists, turns, and devastating fallout.
Jackson Lamb (Gary Oldman) returns as the gruff, sharp-tongued leader of the Slow Horses, his brilliance still hidden beneath a layer of cynicism and cigarette smoke. At his side, River Cartwright (Jack Lowden) and Diana Taverner (Kristin Scott Thomas) navigate treacherous political waters and personal vendettas that blur the line between friend and foe.
When a series of cryptic, unconnected threats descends upon London, the team begins to suspect something far more sinister at play. As they peel back the layers, the Slow Horses uncover a conspiracy that doesnβt just threaten national securityβit strikes at the very heart of MI5. The deeper they dig, the clearer it becomes: the enemy might not be outside the agencyβ¦ but inside it.
Expect the signature dark wit and razor-edged dialogue that fans have come to love, alongside moments of unexpected vulnerability and gut-punch betrayals. This season leans into its noir roots, offering a chilling portrait of espionage where nothing is sacred, and loyalty is a dangerous illusion.
With its tightly written plotlines, powerhouse performances, and unrelenting tension, Slow Horses: Season 5 promises to be a gripping ride from start to finish. Spy games donβt get colderβor more personalβthan this.
