This ambitious documentary follows the circuitous route of the 1,100-mile BTC Pipeline, a string of 150,000 steel pipes that links the cities of Baku, in Azerbaijan; Tbilisi, in Georgia; and Ceyhan, in Turkey. The pipeline will transport the rich, previously untapped energy reserves of the Caspian Sea to the Mediterranean, from where it will flow into the global market, but its route makes many detours around areas of regional conflict and territorial dispute. Traveling the pipeline’s length, the filmmakers encounter numerous stumbling blocks—including their own arrest in Azerbaijan—as they make their way through some of the most geographically challenging and politically unsafe places on Earth.
