'Herdswoman' is a portrait of three Sami women to whom reindeer herding is more than a mere occupation. It is a way of life, their culture. Aina, Elisabeth and Lisa belong to different generations. Their stories function as reflections of life in Sápmi (Lapland) and the transition from nomadic existence to modern society. The film illustrates their pleasure in working with the reindeer. The women raise questions about the essence of life by sharing their thoughts, dreams and memories, which reflects their world views and values. When a court case questions their ancient rights to the reindeer pasture, their livelihood and culture is sat at risk. The film portrays the indigenous peoples' vulnerability in modern society and the process of globalization and colonization, which has led to the present conflict on land and water rights.
