Narrated by Award-Winning actor Andy Serkis, this film takes viewers on a journey of a lifetime to explore the world of the magnificent blue whale, a species rebounding from the brink of extinction. Blue whales are the largest animals ever to have lived, bigger than any dinosaur, yet we know surprisingly little about them. The film follows two scientific expeditions: one, a high-risk mission to find a missing population of blue whales not seen in 50 years; and the other, to join Diane Gendron, the “Blue Whale Whisperer,” in Mexico’s Gulf of California, where she and her team explore the important role these remarkable animals play in the health of our oceans. The film provides an unforgettable window into these animals’ lives—and the extremes scientists must endure to study them.
