In the jungles of northwestern India lies an ancient 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.

In the 1990s, conservationists in India began noticing something unthinkable: tigers they had tracked for years were disappearing. They soon discovered that poachers had returned.

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.

When a female tiger’s behavior becomes dangerous and unpredictable, researchers are left puzzled. Weeks later, the reason reveals itself.
