With less than a month until Slow Horses Season 3 arrives on Apple TV+, the trailer for the new season has finally arrived. Based on the popular series of spy novels by Mick Herron, the series follows the story of a dysfunctional team of British intelligence agents who’ve all been reassigned to serve in a dumping ground department of MI5 known un-affectionately as Slough House. Oscar winner Gary Oldman stars as Jackson Lamb, the brilliant but irascible leader of the group, who have all essentially been removed from the field for various career-ending mistakes and are desperate to find their way back. 

Supposedly condemned to spend their lives paper-pushing, they’re so bored that they catch the details that regular spies are too busy to notice. Season 3 will be based on the third book in Herron’s series, Real Tigers. The series, which has already been renewed through Season 4, has become something of a sleeper hit or the streamer, steadily building an audience and garnering increasing critical interest and acclaim through its recently completed second season. In the upcoming third season, Lamb’s disgraced spies must work together to foil a rogue agent when one of their own is kidnapped. 

The trailer shows what it looks like when these guys go rogue.

Here's the Season 3 synopsis:

The series is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known un-affectionately as Slough House.

In Season 3, adapted from Real Tigers, the third novel in the Mick Herron series, a romantic liaison in Istanbul threatens to expose a buried MI5 secret in London. When Jackson Lamb and his team of misfits are dragged into the fight, they find themselves caught in a conspiracy that threatens the future not just of Slough House but of MI5 itself.
