After an undercover investigation into animal cruelty led to a ban on traveling animal circuses in Bolivia, circus owners continued to defy the law. LION ARK follows one of the worlds most ambitious and daring animal rescues ever made and documents the harrowing events as they actually unfold. The team behind the investigation returned, tracked down the illegal circuses and saved every animal, airlifting 25 lions to freedom in Colorado. This uplifting story of bravery, compassion, camaraderie and determination proves how a poor but proud country can say no to animal cruelty and how attitudes toward animals can be changed across an entire continent.
