The story of Dirty Lines starts in 1987's Amsterdam, at a time when Dutch society was changing rapidly. Psychology student Marly Salomon takes on a side job working for a brand new firm: Teledutch - a company started by two brothers, Frank and Ramon Stigter, who established Europe’s first erotic telephone lines. Frank and Ramon become rich overnight and Marly finds herself immersed in this wild and rapid transformation.
