The walrus is one of the Arctic's most enigmatic animals. With three-foot long tusks and a droopy mustache, everyone knows what these marine mammals look like, but few ever see them in the wild. For Kirk Johnson, a paleontologist and Sant Director of the Smithsonian National Museum of Natural History, the walrus has been a creature close to his heart for 40 years. Most of the world's walrus, about 250,000 of them, live in the frigid seas between Russia and Alaska. Johnson embarks on an Arctic adventure to uncover the hidden lives of these lumbering giants and the threats they face as climate change shrinks the sea ice. He follows the fate of one young orphan, who is rescued and rehabilitated at the Alaska Sealife Center. What kind of future lies ahead for her, and for the walruses in the wild?

Against the backdrop of Africa's Mount Kilimanjaro, meet the majestic 'super tuskers'- male elephants that carry the wisdom of generations, whose tusks each weigh at least 100 pounds. Fewer than 30 remain in all of Kenya. Follow the lives of Craig, Pascal, and Esau - tuskers at different stages of life - as they navigate the trials, transformations, and experiences that come with age and a shifting landscape. The film offers a rare window into a world of male African elephants: the annual cycle of musth, a period of heightened hormones for breeding and asserting dominance, as well as tender moments among old friends. Across the open plains of Amboseli National Park and beyond, the bulls must find a balance between independence and the deep social bonds of brotherhood. Their stories reflect a lifetime of survival and strength-shaped by decades of navigating drought, conflict and human-wrought change. 'To enter the world of male elephants was astonishing,' said Allison Argo, writer and producer. 'Most of us are aware of female elephants and their wonderful matriarchy, but male elephant society is equally fascinating and complex. To be allowed into their world is a huge privilege- and with that comes a responsibility to protect them.'

In the jungles of northwestern India lies an ancient structure, Ranthambore Fort, that has stood for more than a thousand years. For centuries, rulers battled over its control. Today, it is home to the most filmed and studied tigers on Earth. This is their story, told by the man who's devoted his life to keeping them alive. Ranthambore National Park is known for its spectacular wildlife, specifically its magnificent tigers. Centuries of hunting had driven the tigers into hiding, forcing them to live like ghosts. Then protected by Prime Minister Indira Gandhi's ban on hunting in the early 1970's, these tigers have grown from a group of a dozen cats into a clan of more than 70 members. For the last half-century, one man followed, photographed and filmed them: one of the world's leading tiger experts, Valmik Thapar. Although Thapar passed away in May 2025, he was able to collate his archive, with the help of friends and family, to tell the definitive story of this tiger dynasty for the first time. Witness rare behavior and unbelievable footage of dramatic and intimate moments between five generations of tiger matriarchs.
