If global warming doesn’t have you thinking about Armageddon, a new documentary by two Bolinas filmmakers will. But even as the film focuses on the various horrors of nuclear power, from Chernobyl to Fukushima, it won’t leave viewers feeling hopeless. “SOS—The San Onofre Syndrome: Nuclear Power’s Legacy” was produced by Mary Beth Brangan and James Heddle, a longtime Bolinas couple who have been making films with an activist bent for four decades. It chronicles the battles of citizen activists who successfully fought to shut down the San Diego County nuclear facility only to confront the ongoing threat posed by the 3.55 million pounds of high-level nuclear waste that remain there. It is told through the eyes of five ordinary people who armed themselves with information and pushed officials from San Diego to Washington, D.C., to decommission the plant, located on a narrow stretch of picturesque shoreline between Interstate 5 and the Pacific. The Beach Boys once referenced that very stretch of coast in a song before it became better known for uranium than surfing. The film has been honored with several documentary filmmaking awards. It includes harrowing scenes from the aftermath of the Fukushima Daiichi nuclear meltdown, which was unleashed after an earthquake and tsunami in March 2011. Radioactive material carried across the Pacific was soon detected off the West Coast, prompting one of the film’s protagonists to buy a Geiger counter, fearing for the health of his three children. When he checked a half-empty gallon of milk in the refrigerator, the device began detecting radiation. “It was clicking kind of vigorously,” he says. “I looked at my wife and I said, ‘I think I’ve been feeding our kids radioactive milk.” That’s when his activism began. He and the film’s other protagonists take to heart an insight from Frederick Douglass that is invoked at the end of the film: “Power concedes nothing without a demand. It never did, and it never will.” The film will have its West Marin premiere at 5 p.m. on Sunday, May 19, at the Bolinas Community Center. $10 to $25 tickets at https://tinyurl.com/BolinasDoc.
