- Apple TV’s Season 6 trailer sends the Slough House team into hiding, reveals Sid’s return and sets a September 16, 2026 launch.
Apple TV has released a trailer for the sixth season of “Slow Horses,” confirming that the spy drama will return on September 16, 2026.
The preview shows Jackson Lamb and the Slough House team forced into hiding as an unidentified threat targets members of the group. It also signals the return of Sid, played by Olivia Cooke, a familiar character whose reappearance is a central reveal in the new footage.
The series follows a group of sidelined British intelligence officers working under Lamb. The trailer provides the clearest look yet at the danger facing the team in the coming season, while leaving the identity and motive of their pursuer unresolved.
