In short: What began as a 2007 novel by former SAS soldier Chris Ryan transformed into a sprawling, multi-series action thriller. Following the high-stakes missions of the secretive Section 20, the franchise evolved from a six-part British series into a massive international co-production spanning eight seasons of global warfare.

The franchise's origins lie in the 2007 novel by Chris Ryan, a former Special Air Service soldier. When the television adaptation premiered on Sky One on 5 May 2010, it saw immediate success, with the premiere attracting nearly 400,000 viewers—tripling the channel's average audience share for that time slot. This momentum led to a significant expansion, with Cinemax joining as a co-producer for the second series, which aired on 12 August 2011.

The narrative centers on Section 20, a clandestine branch of the British Secret Intelligence Service (SIS/MI6). The series follows operatives through increasingly complex geopolitical conflicts, ranging from the aftermath of the 2003 invasion of Iraq to nuclear disarmament tensions in North Korea and the pursuit of rogue biochemists in Hungary. Early storylines focused on John Porter, played by Richard Armitage, whose career was derailed after a mission in Iraq where he spared a young suicide bomber who subsequently killed two of his teammates.

As the show progressed through various iterations—including 'Vengeance', 'Shadow Warfare', 'Legacy', 'Retribution', and 'Revolution'—the scale of the threats escalated from localized terrorist cells to global conspiracies involving the CIA, the IRA, and even the North Korean military's Office 39. Despite production delays, such as the one in 2015 caused by an injury to star Sullivan Stapleton, the series maintained a high-profile presence across both Sky One and Cinemax until its conclusion with the eighth series, 'Vendetta', which premiered on 14 February 2020.
