An exhausted 2 Section retreat to Kabul only to be ordered to support Elvis in a final mission to capture Omar.

Georgie and the others must wait bravely as the ruthless Boko Haram rebels beat the Nigerian military members of their group. With their fate seemingly teetering on a knife edge, they are shocked when they discover that the local crime boss is in fact an undercover SF operative. As he relays a plan to them, back at base James is equally shocked to discover that the mercenary is also one of the undercover SF unit named Bones and is an old acquaintance from Sandhurst - and someone with whom he has history. As Georgie and the others are freed in a stunning operation, 2-section and Special Forces work on recovering the beaten and imprisoned Nigerian military medic, trading him for the rebel leader's son who has been detained by 2-section. A tense stand-off ensues, with the rebels booby-trapping the prisoners. Will they all make it out alive?
