Watch Slow Horses Season 4: Synopsis
Dark secrets, assassination attempts, and doddering old spooks. Yes, the acclaimed spy drama is back and the MI5 rejects at Slough House are feeling the pressure once more. Based on Mick Herron’s fourth entry in the Slough House series, the Cartwright family discover that past misdeeds have life-threatening repercussions in the present, in what looks to be the show’s most thrilling, high-stakes season yet.
The titular “Slow Horses” refer to those MI5 misfits condemned to the administrative doldrums of Slough House for their grade-A cockups. Among those stuck doing The Park’s grunt work are River Cartwright, Louisa Guy, and tech genius Roddy Ho. They’re frequently berated by resident nag Jackson Lamb, the flatulent yet brilliant Head of the Horses played by Academy Award-winner Gary Oldman.
After last season, we can expect a dramatic shake-up in MI5’s hierarchy. Former Director of the MI5, Ingrid, resigned following the botched execution of her brutal cover-up operation, and “Second Desk” Diana (BAFTA-winner Kristen Scott Thomas) seemed a shoo-in to replace her. Meanwhile, Catherine Standish angrily quit, and both Shirley Dander and Marcus Longridge were sent packing. But the belligerent Lamb is almost certain to hire them back.
Based on Herron’s Spook Street, Season 4 begins with a suicide bombing at a London shopping center. It’s an incident that rocks the service, and its links to ex-agent David Cartwright (Jonathan Pryce) and his grandson River (Jack Lowden) threaten to expose the shady dealings of the Cartwright family.
New to the series are Hugo Weaving (The Matrix), a former CIA agent turned mercenary who may or may not be assembling an “assassination squad,” in addition to Ruth Bradley (Ted Lasso), MI5’s new head of internal security and a great sparring partner for Lamb. On first meeting, she rather accurately nails him as “a man who looks like he gropes people on buses.”
Described as “one of the great shows to come out of Britain full stop” by the London Evening Standard and boasting an incredible 100% on Rotten Tomatoes, the latest instalment of Slow Horses looks to be as compelling, propulsive, and action-packed as ever.
