The official trailer for Slow Horses Season 6 sends Jackson Lamb and his dysfunctional team of MI5 agents back into the dangerous world of British espionage, where mistakes can have consequences far beyond Slough House.
Gary Oldman returns as the brilliant, abrasive, and perpetually disheveled Lamb, leading a group of intelligence agents whose career-ending failures landed them at MI5's least prestigious outpost. They may be the service's rejects, but trouble has a habit of finding them—and Season 6 is no exception.
Slow Horses Season 6 premieres September 16, 2026, on Apple TV.
