Spanish historical adventure about the hunt for a soldier whose actions caused Napoleon's first defeat. In 1808, at the height of Napoleon's campaign against the Spanish, a single military drummer causes the French army to panic and retreat when he uses the Monserrat mountains to echo the sound of his drums. After hearing of his army's humiliating defeat, Napoleon demands the drummer's head, and dispatches an elite band of his most deadly imperial guards to track down the young hero at any cost.
