The story of the Jesuit martyrs who lived with the Wendat converts in the region near what is now Midland, Ontario. The film is of wide interest since it reconstructs a period of Canadian history, especially of Indigenous life, at the very beginning of European settlement. The village and the Jesuits' buildings are exact models from archeologists' reconstructions. The story is based on the Jesuit Relations, the actual journals of mission life that still make for thrilling reading.
