The Doctrine of Discovery began as a set of 15th-century papal decrees granting Christian explorers the right to claim any land not already occupied by Christians, and this film traces how that legal doctrine still underpins property law, treaty disputes, and court rulings in the United States and Canada. Indigenous leaders, scholars, and clergy explain how the doctrine justified the seizure of Native lands from first contact through the Supreme Court's 1823 Johnson v. M'Intosh decision, which cited it directly and remains cited today. The film moves between historical documents, interviews on reservation land, and accounts of contemporary struggles over sovereignty and territory that trace back to this centuries-old legal framework. Church representatives, including voices from denominations that have since repudiated the doctrine, discuss its religious origins and ongoing consequences. Rather than treating this as settled history, the film argues the doctrine is a living legal principle still shaping court decisions, and follows Native activists pushing governments and churches to formally renounce it.
