Josh Tickell spends eleven years crossing the country in a converted school bus running on biodiesel, using the trip as the spine for a history of America's addiction to oil. Archival footage traces the industry back to Rockefeller and shows Rudolf Diesel's original engine, which was designed to run on peanut oil before petroleum interests rewrote the fuel supply. Tickell interviews environmentalists, scientists, and public figures including Woody Harrelson and Robert Kennedy Jr., who lay out the case for ethanol, biodiesel, solar, and wind as replacements for imported crude. The film does not stay purely celebratory: it also examines the failures and unintended consequences of past alternative-fuel pushes, including corn ethanol's strain on food prices. Tickell's own family history with the oil industry in Louisiana gives the film a personal throughline alongside the policy arguments. Shot over a decade, it plays as both a road movie and an argument for weaning the country off foreign oil before the next price shock or spill forces the issue.
