Linguist Indrek Park has been working with Native American languages for over ten years. The film sees him recording the language of the Mandan tribe, who live in the prairies of North Dakota, on the banks of the Missouri River. The job involves a lot of responsibility, and he is running out of time – his language guide, the 84-year-old Edwin Benson, is the last native speaker of Mandan.
