The episode is an extensive historical account of Prince Eugene of Savoy's military career, focusing particularly on his decisive role in shifting the balance of power in the Balkans away from the Ottoman Empire. It details the context of Ottoman control over much of Southeastern Europe, including the strategic importance of the city of Belgrade at the confluence of the Danube and Sava rivers. The episode explains how Prince Eugene's crucial victory at the Battle of Peterwardein in 1716 preceded the main objective, the siege and eventual capture of Belgrade in 1717, a complex military operation requiring advanced logistics and a risky night attack. Ultimately, the capture of Belgrade and the subsequent Peace of Passarowitz in 1718 are presented as key moments that cemented Austria's status as a major European power while marking the decline of the Ottoman Empire's influence in the region.
