In the early hours of March 24, 1989, the oil supertanker Exxon Valdez, en route from Valdez, Alaska to Los Angeles, California, ran aground, discharging millions of gallons of crude oil into Prince William Sound, Alaska. The incident became the biggest environmental catastrophe in North American history. For 20 years, Riki Ott and the fishermen of the little town of Cordova, Alaska have waged the longest legal battle in U.S. history against the world’s most powerful oil company — ExxonMobil. In this film, they review the environmental, social and economic consequences of the black wave that changed their lives forever. Directed by Robert Cornellier. Produced by Robert Cornellier and Paul Carvalho.
