What Season 5 is poking at
This round opens with Roddy Ho getting a new girlfriend, which, if you know Roddy, sets off alarms louder than any car siren in London. Soon after, odd things start happening across the city. The Slow Horses get yanked into figuring out what connects the weirdness, while Jackson Lamb and River Cartwright end up facing a fresh mess that puts their double act to the test.
The returning crew
Gary Oldman is back as the endlessly irritable Jackson Lamb, with Jack Lowden as River Cartwright. Kristin Scott Thomas returns, Rosalind Eleazar is in the mix, and the rest of Slough House’s walking HR warnings are along for the ride.
Quick refresher on the show
Slow Horses follows the MI5 misfits banished to Slough House and their delightfully toxic boss, Jackson Lamb, as they wade through the espionage swamp to stop threats to the U.K. The team may be sidelined, but they routinely end up being the ones who actually get things done—barely, chaotically, and usually with a hangover.
