Der Film folgt dem realen Fake-News-Skandal von 2018 um den in Ungnade gefallenen Spiegel-Journalisten Claas Relotius.
“A Thousand Lines” – a blend of satire, drama and comedy – is written by Hermann Florin, inspired by Juan Moreno's “Tausend Zeilen Lüge.” It is the fictional adaptation of one of Germany's biggest media scandals.
