Filmmaker James Fox grows frustrated by the lack of plain talk and BP's inability to plug a gushing well after its Deepwater Horizon rig exploded and sank in the Gulf of Mexico. During the summer of 2010, Fox moves among locals across four Gulf states documenting the largest man-made environmental disaster in US history. He flies over ground zero with marine biologist Dr. Carl Safina who warns him that BP is sinking the oil with the chemical dispersant Corexit, sweeping it under the rug. He investigates this further and conducts his own independent water tests to determine toxicity levels. The results show that public safety takes a backseat to a tourism-based economy, and the symbiosis between big oil and government becomes clear.
