In support of Earth Hour, which takes place tonight at 8:30 p.m. local time, the new Disneynature film Born in China has released a short clip. Additionally, the sneak peek is introduced by the band American Authors, who penned a new tune called “Everything Everything” especially for the movie.

World Wildlife Fund (WWF) is one of the organizations behind Earth Hour. Disneynature is working with WWF on behalf of Born in China: moviegoers who see the film during its first week in theaters (April 21-27, 2017) will help protect wild pandas and snow leopards.

Narrated by John Krasinski, Disneynature’s new True Life Adventure film Born In China” takes an epic journey into the wilds of China where few people have ever ventured. Following the stories of three animal families, the film transports audiences to some of the most extreme environments on Earth to witness some of the most intimate moments ever captured in a nature film. A doting panda bear mother guides her growing baby as she begins to explore and seek independence. A two-year-old golden snub-nosed monkey who feels displaced by his new baby sister joins up with a group of free-spirited outcasts. And a mother snow leopard—an elusive animal rarely caught on camera—faces the very real drama of raising her two cubs in one of the harshest and most unforgiving environments on the planet. Featuring stunning, never-before-seen imagery, the film navigates China’s vast terrain—from the frigid mountains to the heart of the bamboo forest—on the wings of red-crowned cranes, seamlessly tying the extraordinary tales together.
