When US network news legend Candida Coulter cascades into Karibu, flanked by her long-suffering cameraman and producer, the American invasion of the conflict-torn African country begins. A turf war for talking heads breaks out between Coulter and her arch-rival, BBC correspondent David Bradburn. However, with bribery, exploding pineapples and power-outages, it is anyone's guess which national news reporter will get to file their story first.

Harry meets his girlfriend Grace's father for the first time. Meanwhile senior correspondent David and new cameraman Rory clash over the uses of root ginger and producer Jane loses her patience after David's passport comes to a sticky end at the hands of the local militia - who soon want much more than a bribe. There's good news as charity worker Samantha organises a traditional summer fete in aid of boy soldiers, Sons Without Guns. However, after a mix-up involving the Beckhams, will Fiona Bruce witness the BBC's Chief Foreign Editor being terminated, live, on air?

When informed from London that military fashion is "in" this season, the team are sent in search of a story about sniper-chic. Their search takes them to an old colonial house and the formidable Mags O'Mara, where they encounter a night of colonial tales, African magic and Strictly Come Dancing.

The team take a trip out to a school. However, things do not go smoothly. The team finds itself caught in the crossfire between government and rebel forces, and thus David is presented with the perfect opportunity to exercise his legendary "Bafta crouch". Meanwhile, a driving lesson ends in a near-death experience as Harry and Grace's relationship goes seriously off-road and she dissects the flaws in the story of the tortoise and the hare.

Much to David Bradburn's dismay, Jeremy Morrison the BBC Brussels Correspondent and media darling arrives in Karibu to report on the new ceasefire. As the world changes around him, David fears for his future. Meanwhile, Jane must try to keep both her "big beasts" happy with just one cameraman between them. Elsewhere, Margaret is recording the sound of a zebra's breath, and Harry is teaching local reporter William how to be a famous TV journalist - until a humanitarian crisis brings them all together.

A new democratic era dawns for the country as the exiled Lion Queen of Karibu returns to a heroine's welcome, a rally and an election. But what does the end of conflict mean for Harry, Grace, Samantha and the Sons Without Guns? What does the future hold for them, and for the country? There's good news and bad as hopeless Harry finally hits his stride but loses his phone, his friends and maybe his future; while David's lack of action in the sack starts to affect his work ... and his colleagues.
