The smartphone documentary features Calin Serban, a Romanian ranger from the Foundation Conservation Carpathia. Their mission is to create a wilderness reserve in southern Carpathia, Romania. A part of the project is the reintroduction of European bison in Romania's Fagaras Mountains, after over two centuries of extinction in the region. It's a compelling story about the critical role of the bisons in revitalizing ecosystems, inspiring coexistence between humans and nature, and the vital importance of biodiversity preservation.

Shot entirely on a smartphone, the video is a testament to the power of storytelling and how it can raise awareness and bring attention to critical environmental issues.
