Four war-veterans, former enemies journey back to past battlefields deep within the African interior in search of reconciliation, forgiveness and ... atonement?

Four war-veterans, from different sides, step onto a boat at the mouth of the Kwando river, deep within the African interior. They are on a journey back to the battlefield, the site of the last "great" battle of the Cold War - its inconclusive and a very secret Armageddon, where they as youngsters, once tried to kill each other. But now, twenty years later, they've come together as former enemies, a new unit of disparate souls joined together not only by the common haunting of war trauma, but also by their need to understand, to reconcile, to forgive.
