On April 20, 2010, an explosion tears through the Deepwater Horizon platform in the Gulf of Mexico, rupturing a wellhead roughly 5,000 feet below the surface. The film uses footage of the spill, much of it rarely seen, to trace what happens next: oil pouring unchecked into open water for nearly three months while engineers attempt one containment method after another. By the time the well is finally capped on July 15, 2010, an estimated 4.9 million barrels have leaked into the Gulf, making it one of the largest marine oil spills on record. The film stays close to the mechanics of the disaster, showing the scale of the leak and the difficulty of stopping it a mile underwater, and uses that footage to make a broader argument about offshore drilling itself. The risks are not abstract here; they are measured in barrels, in weeks of uncontrolled flow, and in images of an ocean floor breach no one could immediately reach or fix.
