"Chaika" — an investigation by Alexei Navalny into the family of Prosecutor General Yuri Chaika, its business dealings, assets, and connections.
The project was released as both an investigative documentary and a dedicated website featuring a written version of the investigation, documents, and additional materials. The investigation focused on Yuri Chaika’s sons, Artem and Igor, as well as companies linked to them, their assets, and business relationships. The website served as a detailed dossier accompanying the film, bringing together documents, sources, key figures, and supporting materials that allowed viewers to verify the investigation’s main findings. Chaika became one of ACF's defining projects of the mid-2010s and an important example of a large-scale investigation presented in the form of a standalone documentary film.
