On the day before a big audition, young actrice Danaé is trying to learn her lines. Everyone else in the city seems to have better plans during the raging heatwave, like house parties or watching the national football team. While Danaé struggles and the audition draws near, the city seems keeps intruding further in her personal space.
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. The final years of the Cold War sparked a sense of hope and inspired a new generation to celebrate life to its fullest. Amsterdam became the center of that cultural revolution with a radically new form of music: house and a new love drug: XTC. The erotic phone lines offer the opportunity to experience anonymous sex in a new way, changing the morality of its consumers, but also very much the people creating it.
Best friends Romano, Potlood and De Paus rise in the rank of the criminal world. Before they know it, they run Amsterdam's entire coke market. Because of jealousy, their relation becomes complicated and ends up hostile.
