Montgenèvre, an idyllic ski resort on the French-Italian border. On paper, the law allows refugees to apply for asylum upon arrival in France. In reality, many are turned back to Italy by the police without ever having the opportunity to file an application. To be able to continue their journey, people take higher and higher routes through the mountains, often risking their lives. On the French side, volunteers of all ages walk the paths every night to offer them help, and guide them to a refuge further down the valley. Nightwatchers provides a direct cinematic experience over one night in the mountains by their side.
