The Caucasus becomes a chessboard in this episode, as the United States and Russia maneuver for control of the oil and gas routes threading through Georgia, Azerbaijan, and Chechnya. The film traces how pipeline politics replaced Cold War ideology as the region's central fault line, with archival footage and interviews laying out how Western oil majors, descendants of the old "Seven Sisters" cartel, pushed to route Caspian oil away from Russian territory entirely. Chechnya's wars are framed not just as ethnic conflict but as collateral damage in a fight over transit corridors, while Georgia's post-Soviet turmoil gets read the same way. Analysts and former officials describe how Moscow used energy leverage and military presence to keep its grip on former Soviet space, and how Washington backed alternative pipeline routes to break that grip. The episode treats the Caucasus as a proxy battlefield where control of roads and pipelines matters more than the ideologies once fought over there.
