Cesium-137 is one of a number of radioactive substances that were released into the environment during the accident at the 4th power unit of the Chernobyl NPP. From Latin the word "cesium" translates as "sky blue". Together with other hazardous substances, this "azure dust" infected the entire Exclusion Zone and subsequently killed thousands of lives.

The creators of the project managed to find two heroes with a unique destiny, who lived in Pripyat at the time of the disaster. They, as well as other inhabitants of the city, were evacuated with great delay. However, despite everything, they were able to survive and show by their example that it is possible to defeat the system and overcome difficult circumstances, thanks to perseverance, hope and faith.

The film is a kind of guide to the Exclusion Zone. Thanks to the unique shots that the authors of the project were able to shoot at the site of the tragedy, viewers will be able to fully immerse themselves in the atmosphere of events and together with the characters feel the terrible and amazing atmosphere that prevails in one of the biggest man-made disasters.

A film from the film series Chosen by Time.
