Slow Horses follows a group of disgraced British intelligence agents, known as Slough House, who are relegated to mundane paperwork as punishment for their career-ending mistakes. They are led by the brilliant but slovenly and offensive Jackson Lamb, a former Cold War legend who runs the unit with contemptuous glee.
In Season 4, the action adapts the novel “Spook Street.” The central plot revolves around a devastating terrorist attack on a suburban shopping center. The Slow Horses find themselves investigating a possible connection to a dormant, decades-old MI5 operation.
The investigation becomes deeply personal for River Cartwright. It leads him to his reclusive grandfather, David Cartwright, a revered former head of MI5 now suffering from dementia. River discovers his grandfather may hold dangerous secrets tied to the attack.
As the team digs deeper, they uncover a web of lies and old vendettas within the intelligence establishment itself. The present-day threat is linked to a rogue agent from the past, trained by David Cartwright, who is now on a lethal revenge mission.
The season balances tense action, such as River’s desperate attempts to protect his grandfather from assassins, with the series’ signature dark humor and the dysfunctional dynamics of the Slow Horses team. Jackson Lamb, while appearing detached, maneuvers in the shadows to outmaneuver the official MI5 powers that despise his team.
Ultimately, the season explores themes of legacy, betrayal, and the long shadows cast by past operations. The Slow Horses, as usual, must work outside the rules to uncover the truth and prevent further catastrophe, all while being scorned by the very institution they are trying to protect.
