On the eve of Russia’s invasion of Ukraine, Ukrainian filmmaker and journalist Mstyslav Chernov and his colleagues, photographer Evgeniy Maloletka, and field producer Vasilisa Stepanenko, entered the strategic eastern port city of Mariupol. During the subsequent siege and assault, as bombs fell, inhabitants fled, and access to electricity, food, water, and medicine were severed, the team struggled to cover the war atrocities and transmit their footage out. Eventually, surrounded by Russian soldiers, they sheltered in a hospital, unsure of how they’d escape.

Chernov offers a window into the practices of conflict zone reporters and an unflinching, anguishing account of their time in Mariupol. Their footage documents the death and destruction. and directly refutes Russian misinformation. Seeing so much death, Chernov wonders how capturing any more could make a difference. But residents implore them to let the world bear witness.

A team of Ukrainian journalists from The Associated Press (AP) trapped in the besieged city of Mariupol struggle to continue their work documenting atrocities of the Russian invasion. As the only international reporters who remain in the city, they capture what later become defining images of the war: dying children, mass graves, the bombing of a maternity hospital, and more. 

After nearly a decade covering international conflicts, including the Russia-Ukraine war for the AP, “20 Days in Mariupol” is Mstyslav Chernov's first feature-length film. Drawing on Chernov's daily news dispatches and personal footage of his own country at war, the film is a vivid, harrowing 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.

Told through the perspective of Ukrainian-born director and AP video journalist Mstyslav Chernov, 20 Days in Mariupol is a visceral, first-person view of the early days of Russia’s invasion of the city of Mariupol, Ukraine. Chernov and his colleagues, photographer Evgeniy Maloletka and field producer Vasilisa Stepanenko were the last international reporters to remain in Mariupol as Russian troops attacked the city. Together they documented what would become defining images of the war: dying children, mass graves, the bombing of a maternity hospital, and more.

Produced and edited by FRONTLINE’s Michelle Mizner, the film draws on Chernov’s daily news dispatches and personal footage of his own country at war. The result is a raw and haunting account of a journalist risking his life to share the truth of the conflict with the world.

Bearing witness to the horrors that enveloped the city, the documentary captures the beginning of the war through the lens of a Ukrainian journalist documenting the devastation of his home country.

Much of Chernov’s video and the visuals from his colleagues have been widely published around the world, from corpses in the streets to panicked, displaced civilians desperate to flee, to grief-stricken parents of children who died from Russian shelling – events reported by AP and FRONTLINE as possible war crimes. The AP footage also directly refutes Russian misinformation about the war.

Chernov has covered Ukraine and other international conflicts for The Associated Press for nearly a decade. “20 Days in Mariupol” is his first feature film.
