Slow Horses Season 3

"Slow Horses" is a sharply humorous espionage drama centering on a group of British intelligence agents relegated to a disregarded branch of MI5 — a veritable purgatory for operatives sidelined by their blunders. In its third season, a clandestine affair in Istanbul risks unearthing a long-concealed secret within the MI5 headquarters in London. When Jackson Lamb, portrayed by Academy Award winner Gary Oldman, and his band of outcasts are pulled into the fray, they become entangled in a conspiracy that poses a dire threat not only to the survival of Slough House but to the very foundation of MI5 itself.
