Trillium (2018)

There are about 250 people with a unique ancestry. Livonians – one of the smallest and most endangered nations. Each of Livonians has a duty to preserve their identity and the great history of their ancestors. Trillium follows the footsteps of a poet and researcher Valts Ernštreits, who is one of 20 people able to speak fluent Livonian – an indigenous language related to Estonian and Finnish – in his efforts to look after the language and culture of these ancient settlers of the Baltic Sea coast.

Unfortunately the movie Trillium is not yet available on HBO Max.
