The trailer for Netflix's next original documentary has some harrowing — but important — images.

Winter on Fire: Ukraine's Fight for Freedom chronicles a 93-day period in 2013 and 2014 that saw a civil rights movement morph into a millions-strong revolution and civil unrest.

It features interviews with protestors, on-the-ground footage, and a "grand scale" look at the violent conflict, according to Netflix.

The film, directed by Evgeny Afineevsky, premieres Oct. 9.

Netflix has also released an official poster, which you can see below.
