This hit spy thriller follows Jackson Lamb and his team of sidelined MI5 agents as they face escalating dangers. Meanwhile, Diana Taverner struggles to maintain control after becoming First Desk.
The season finale is the sixth installment in a weekly release schedule that began on September 16. While Apple TV officially lists Wednesdays as the global release days, new episodes frequently become available at 9 p.m. ET on the evening before their scheduled release date. This gives fans an early look at the action.
What Happened Before the Season 6 Finale?
The fifth episode, “Sayonara,” aired on October 14. It intensified the conflict surrounding Diana Taverner’s controversial decisions and placed agents Sid Baker and River Cartwright in immediate physical danger. Head writer Gaby Chiappe and the cast have teased that “Judgment Day” will bring high-stakes danger. This follows the shocking death of J.K. Coe earlier in the run, raising fears of more casualties.
Adapted from Mick Herron’s novels Joe Country and Slough House, the sixth season centers on disgraced MI5 agents forced on the run. They are dragged into a deadly game of retaliation. The latest run features the return of series regulars Gary Oldman as Jackson Lamb, Jack Lowden as River Cartwright, and Kristin Scott Thomas as Diana Taverner. Olivia Cooke also reprises her role as Sid Baker for the first time since Season 1.
