After Slow Horses became a hit on Apple TV Plus in the spring 2022, fans didn't have to wait long for the next mission at Slough House, as Slow Horses season 2 is now available on the streaming service.

Slow Horses season 1 was well received by critics and audiences, with the series receiving a 97% from the former and an 89% from the latter, per Rotten Tomatoes; you can check out What to Watch's review of Slow Horses here. The show is part of a recent string of well received new series from Apple TV Plus, like Severance, The After Party and Pachinko, to go along with Apple TV Plus' flagship series, Ted Lasso.

What's next for the Slough House team? Here is everything you need to know about Slow Horses season 2.

When is the next Slow Horses season 2 episode?

The Slow Horses season 2 finale is now available to stream on Apple TV Plus, or if you've been waiting for all six episodes to become available, you can now binge the entire season.

Here is the synopsis for Slow Horses season 2 episode 6, "Old Scores":

"Lamb and Katinsky go head to head. Ho finds himself trapped on a train with a Russian assassin."

Slow Horses season 2 plot

Slow Horses is based on Mick Herron's Slough House series of spy novels, which focus on a group of disgraced MI5 agents that form an unlikely team when it comes to saving the day. Season 1 was based on the first book, Slow Horses.

It makes sense then that Slow Horses season 2 is going to be adapted from the second book in Herron's series, Dead Lions. Here is the official synopsis for the new season from Apple TV: 

"In season two, long-buried Cold War secrets emerge which threaten to bring carnage to the streets of London. When a liaison with Russian villains takes a fatal turn, our hapless heroes must overcome their individual failings and raise their spy game in a race to prevent a catastrophic incident."

Slow Horses season 2 cast

Just about everyone from Slow Horses season 1 is returning for season 2, including Gary Oldman as the head of Slough House, Jackson Lamb. Lamb started out as the boss who epitomized Slough House's who-gives-a-crap attitude, but we saw throughout season 1 that he is still a capable spy. He seems more ready to get back into the game in season 2, but he still has his trademark put-downs ready to go. Oldman has been acting since the '80s, and while he still has Christopher Nolan's Oppenheimer coming up, the Oscar-winner recently said he is considering retirement after Slow Horses ends its run (whenever that may be).

The rest of the Slow Horses are also back, including Jack Lowden as River Cartwright, Saskia Reeves as Catherine Standish, Rosalind Eleazar as Louisa Guy, Dustin Demri-Burns as Min Harper and Christopher Chung as Roddy Ho. 

Other season 1 characters set to return are Kristin Scott Thomas as Diana Taverner, Jonathan Pryce as David Cartwright, Freddie Fox as Spider Webb and Chris Reilly as Nick Duffy.

As far as new actors joining the show, they include Samuel West (All Creatures Great and Small), Aimee-Ffion Edwards (Peaky Blinders), Kadiff Kirwan (This Is Going to Hurt) and Rade Serbedzija (The Blacklist, Taken 2), who is set to play the antagonist on the season.

Will there be a Slow Horses season 3?

Even before Slow Horses season 2 debuts on the streaming service, Apple TV Plus has officially renewed the spy series for a third and fourth season. Not only that, but they also gave us the synopses for season 3 and season 4.

Season 3 will see the disgraced spies work together to foil a rogue agent when one of their own is kidnapped. This appears to follow the third of Mick Herron's Slough House series, Real Tigers.
