Slow Horses Season 5 Trailer Sets Stage for High-Stakes Spy Drama
Apple TV+ has unveiled the trailer for the fifth season of Slow Horses, teasing a battle against an internal threat that could destabilize the country. The series returns globally on September 24, 2025.
The critically acclaimed spy drama Slow Horses is back, and its latest trailer signals that the disgraced MI5 agents of Slough House are once again in the crosshairs of danger. Produced by Apple TV+, the new season promises a tense storyline centered on an “old MI5 destabilization strategy” turned against Britain itself.
Gary Oldman returns as the acerbic Jackson Lamb, still leading his ragtag team of outcasts. The trailer reveals a hacking breach and a ticking clock scenario, ratcheting up the tension that has defined the show’s success since its debut. Oldman’s performance has already earned Emmy recognition, and this season seems poised to deepen Lamb’s reputation as the ultimate anti-Bond.
Joining him are familiar faces Jack Lowden as River Cartwright and Kristin Scott Thomas as Diana Taverner, alongside Saskia Reeves, Rosalind Eleazar, Christopher Chung, and Joanna Scanlan. Their uneasy alliances within MI5 and beyond continue to fuel the series’ blend of dark humor and sharp political commentary.
Season 5 draws inspiration from Mick Herron’s 2018 novel London Rules, part of the acclaimed “Slough House” series. Fans of the books can expect another faithful yet suspenseful translation to the screen, with plotlines layered in bureaucratic dysfunction, loyalty tests, and espionage intrigue.
Apple TV+ will premiere the first two episodes on Wednesday, September 24, 2025, followed by weekly installments through October 22. The rollout echoes previous seasons, keeping audiences on edge week by week.
Over the years, Slow Horses has carved out a reputation as one of the smartest espionage dramas on television. Its BAFTA wins, Golden Globe nods, and multiple Emmy nominations highlight its impact in a genre often dominated by flashier franchises.
The trailer also underscores the series’ unique tone: gritty realism, flawed characters, and sharp political satire, a combination that continues to resonate with viewers. With high stakes and a ticking clock, Slow Horses Season 5 looks set to deliver another compelling chapter in the story of Slough House.
