As ranger Danette Perez starts her second year at Zion National Park she records the ins and outs of life in the desert southwest. Under the scorching summer sun herds of bighorn sheep roam free, twisted slot canyons beckon the brave, and bats take wing under the glittering night sky. In this small corner of land visited by thousands of people a day, the spirit of wilderness lives on in the immense walls of red sandstone and the smallest of lizards scampering by. Recording her own journey, she reflects on life in the park and the desert world, as the seasons for each begin to unfold.
