An MI6 agent called John Allen ends up takeing Stonebridge and Scott from Vienna on a dangerous mission to Kosovo.

In Kosovo, Stonebridge, Scott and four hostages find themselves in dire straits after being double-crossed by KFOR soldiers and the drug lord Hasani.

Enjoying a long-deserved vacation, Scott and Stonebridge are recalled after a fellow Section 20 member dies while pursuing the elusive terrorist al-Zuhari in Beirut. A new lead sends them into the remote jungles of Colombia in pursuit of a known associate of al-Zuhari’s and deep in territory controlled by a powerful drug cartel.

Out of options and hunted by the resourceful cartel, Section 20 goes for a longshot and attempts an assault in downtown Bogota, hoping to obtain intel on one of al-Zuhari’s key people. Meanwhile, Dalton looks for the source that exposed her team in Beirut, but discovers a surprising ally and a piece of al-Zuhari’s plan.

The team tracks stolen property to Russia, where Scott and Stonebridge continue their side careers as "outlaws." As Stonebridge's health continues to deteriorate, they discover new mysteries about a piece of Al-Zuhari's plan. Kamali worries that his cover identity may not hold.
