The Yasin Bey is a ship that doubles as a power plant, a floating turbine hall built to plug into a country's grid wherever electricity is short. This film follows her four-week voyage from Turkey to Indonesia, where local demand has outrun the capacity to generate it. Cameras stay with the crew through the engine rooms and control stations that keep the vessel's generators running at sea, and through the logistics of mooring her at an Indonesian port and wiring her into the national grid. Engineers and crew members explain how a ship this size is converted into a power station, what it takes to keep it fueled and running continuously, and why countries lease these vessels rather than building conventional plants on land. The voyage itself, through open water and into harbor, gives the film its structure, with the technical explanation of how the ship generates and delivers power woven in as the journey unfolds. It is a close look at an unusual piece of energy infrastructure most viewers will never have heard of.
