Recovering after the ordeals of both Afghanistan and Nigeria, Georgie and 2 Section find themselves in Belize for a jungle training exercise and hopefully some much-needed R & R. But when Georgie learns that James has seemingly criticised her in a report into Elvis's death, she becomes angry and distant. Wanting to prove herself a capable leader on the training exercise, she leads a team against James to settle a score, but is forced to step up when events take a turn for the worse. 2 Section retreat back to base to raise the alarm, while Georgie and James must work together to evade the wrath of a lethal drug gang who are operating nearby.

Six months on from Captain James's accident and 2 Section find themselves under the brutal command of the recently demoted Bones. Keen to toughen them up, he also wants to show the brigadier he's capable of leadership. They get to work in a refugee camp run by Barsha Chowdhrey, the wife of the local police chief. Inspector Chowdhrey is known for his hatred of the corruption in the region and at a gala held for the Brigadier, he becomes the target of an assassination attempt. 2 Section are forced to act.
