From executive producer James Cameron and narrated by Sigourney Weaver, Secrets of the Whales follows photographer Brian Skerry as he ventures into the world of whales to reveal life and love from their perspective. The first program of this four-part event tells the stories of five whale species—orcas, belugas, narwhals, sperm whales, and humpbacks. Viewers witness whales making lifelong friendships, teaching clan traditions to their young, and grieving the loss of loved ones.
