This white-knuckle spy thriller of a documentary uncovers a horrifying secret in a little seaside town in Japan. To the unsuspecting, Taiji looks like the dolphin capital of the world, with dolphin images dotted all over town and the real creatures cavorting in its picturesque cove.  But what few know is that beneath the calm surface of the water lurks a devastating practice—the systematic capture and slaughter of thousands of dolphins a year, their mercury-laden meat sold in markets as another kind of seafood. Enter Ric O’Barry, the former dolphin trainer renowned for his work on Flipper, National Geographic photographer Louie Psihoyos, and a team of intrepid filmmakers, specialists, and free divers, who set out with undercover cameras and underwater microphones to expose the ugly truth behind this seeming paradise. They keep you on the edge of your seat until the film’s final moments. You will never look at a dolphin or a plate of seafood in the same way again. ST
