High School will be based on the bestselling memoir by Grammy-nominated, Platinum recording artists and identical twin sisters Tegan and Sara Quin. Written by DuVall, who will direct the pilot, "High School is a transcendent story of first loves and first songs," per Deadline. "Through a backdrop of 90s grunge and rave culture, the series tangles itself in the parallel and discordant memories of two sisters growing up down the hall from one another. This is a story about finding your own identity — a journey made even more complicated when you have a twin whose own struggle and self-discovery so closely mimics your own." Tegan and Sara will serve as executive producers.
