In 1879 South Africa, the administrators of the British Cape Colony have designs to eliminate the Zulus as a hindrance to their colonial economy. To that end, the British present King Cetshwayo with an impossible ultimatum to provoke a war they are sure they can win easily with their rifles and artillery against native spears. However, that war proves more difficult than the arrogant British commander, Lord Chelmsford, expects as his overburdened army fruitlessly searches for the elusive enemy. However, in the shadow of a hill called Isandlwana, the overconfident British army learns to its sorrow just how badly they have underestimated the tactical skill and might of the Zulu nation.

Two Lieutenants, Chard of Engineers and Bromhead find that their 140 man contingent in Natal has been isolated by the destruction of the main British Army column and that 4,000 Zulu warriors will descend on them in hours. Each has a different military background in tactics and they are immediatly in conflict on how to prepare for the attack. Nearly a third of the men are in the infirmary, as the welsh company tries to somehow survive with no help in sight. Based on a true story.
