Based on a true story. In February 1939, Switzerland closes its borders to Jewish refugees. Hundreds of people continue crossing the border without a valid visa. An investigation is launched by the Chief of the Swiss immigration authorities to look into the illegal border crossings. Police inspector Robert Frei, a young, ambitious official who believes in authority, is summoned to the canton of St. Gallen. There, he finds out that Paul Grüninger is letting refugees in without a valid visa, forging documents, and bringing refugees over the border illegally. Grüninger is doing this out of pure humanity. Grüninger’s defiance and the sight of the refugees seeking help make Frei doubt his mission. Should he present his report to a superior, or cover for Paul Grüninger?
