The daughter of Thailand's British ambassador is kidnapped, so Stonebridge, Scott and the rest of the team sign up for another do-or-die trying adventure.

Section 20 try to track down the real culprits behind the embassy attack, starting with getting information from gangster Ray McQueen.

Locke works out that his long-time friend is working with the dangerous Yakuza and Office 39. Scott needs protect his son after they find themselves enemy fire.

Scott has a serious talk with his son whilst the rest of Section 20 form an uneasy alliance with a couple of CIA mercenaries as they go after Shiro and Mei Foster.

Scott and Stonebridge make a major mistake and fall into the clutches of North Korean agent Li-Na, leaving Locke having to defy orders to get them out.

Scott and Stonebridge make a major mistake and fall into the clutches of North Korean agent Li-Na, leaving Locke having to defy orders to get them out.

The team find out that Li-Na is planning to mount a nuclear attack in Europe. Locke puts himself in the firing line after he neglects the mission in order to avenge his son's murder.

Locke takes Section 20 off the radar, as they defy Whitehall to travel to Geneva where he is convinced that Li-Na and Kwon are preparing to attack the United Nations HQ.

Scott and Stonebridge are stranded in the Alps with the mercenaries in pursuit. Scott knows that the CIA hide weapons caches across Europe, so they find a telephone at the farm of a retired Austrian soldier Oscar (Wolf Kahler) to call Christy Bryant (Stephanie Vogt), a past acquaintance from Vengeance, for the location of the nearest one, at a nearby dam.
