On a Berlin construction site, the former editor-in-chief Karin and her journalist Rommy happens to witness a fatal accident. From Taras, the accident victim's brother, they learn that this is not an isolated coincidence: The Eastern European workers who toil on the construction site for cheap wages have to do their day's work under the most precarious conditions and beyond give a large part of their wages to shady "intermediaries".
Unfortunately the movie Tödliche Geheimnisse - Das Versprechen is not yet available on HBO Max.
