Bud Werner Library presents a free community screening of “20 Days in Mariupol” — this year’s winner of Best Documentary at the Academy Awards and BAFTA, plus the the Audience Award winner at Sundance.

The film screens at 7 p.m. Monday in Library Hall. It was made by a team of Ukrainian journalists inside the Russian siege of Mariupol, an extraordinary account seen through the lens of Mstyslav Chernov and two colleagues as they document the atrocities and their own escape.

As the only international reporters who remain in the city as Russian forces close in, they capture what become some of the most defining images of the war: dying children, mass graves, the bombing of a maternity hospital and more.

The film draws on Chernov’s daily news dispatches and personal footage of his own country at war. It offers an account of civilians caught in the siege, as well as a window into what it’s like to report from a conflict zone and the impact of such journalism around the globe.
