Netflix has ordered Dutch original series “Dirty Lines,” about the rise of erotic phone lines in the late 80s. The screenplay, inspired by Fred Saueressig’s book “06-Cowboys,” is written by Pieter Bart Korthuis (“Fighter’s Heart,” “Penoza”) and produced by Amsterdam-based production company Fiction Valley. The series tells the story of young businessman Frank Stigter. After several unsuccessful attempts to start his own business, Frank sees his chance when the national telephone company PTT introduces premium-rate numbers. With the help of his brother and sister and some dubious investors, he starts the first telecom sex company in Europe. What starts as a clumsy improvized experiment in their parents’ garage, rapidly develops into a multi-million dollar industry.
