Apple TV (formerly known as Apple TV+) is a subscription video streaming service for $14.99 per month, offering a growing slate of original series, films, documentaries, and specials. Unlike other platforms that combine licensed titles with originals, Apple TV is built entirely around exclusive programming, making it the home of critically acclaimed hits such as “Ted Lasso,” “Severance,” “The Morning Show,” and “Silo.” Its lineup continues to expand with award-winning dramas, comedies, family-friendly shows, and blockbuster original films like “CODA,” which won the Academy Award for Best Picture.

What is ‘Slow Horses’ Season 6 about?
Apple is keeping much of the plot of “Slow Horses” Season 6 under wraps, in typical spy fashion. But it has shared that this season, the operatives of Slough House will be sent on the run as Diana Taverner embroils them in a fatally high-stakes game of retaliation and revenge. From the trailer, it appears that current and former members of the Slow Horses are being assassinated, meaning that Jackson Lamb has to keep his motley bunch of spies safe while he figures out who is out to get them and why.
The trailer also teases the return of Olivia Cooke’s Sidonie “Sid” Baker, who was presumed dead in Season 1. However, anyone who paid close attention knew that the elite-level agent almost certainly survived.
Since it has been reported that this season will be based on Mick Herron’s novels “Joe Country” and “Slough House,” fans of the books have an insight into what is in store for our inept heroes, but it is still always thrilling to see it play out on screen.

What happened in ‘Slow Horses’ Season 5?
Season 5 of “Slow Horses” started with a major surprise — Slough House’s resident hacker Roddy Ho got himself a girlfriend. But soon enough, she’s exposed as a foreign agent who uses him to steal highly classified MI5 secrets that could destabilize entire nations.
Meanwhile, London is crippled with cyber attacks and mass shootings, and things build toward a final, catastrophic casualty event. But in typical Jackson Lamb fashion, the leader of the Slow Horses manages to outmaneuver his superiors, foil the attack, and finally oust the bumbling Claude Whelan so that Diana Taverner can finally slide into the chair of First Desk.
