Blondie's album Parallel Lines captured the spirit of 1970s New York at a time of poverty, crime and an exploding artistic life, selling 16 million copies. This is the story of that album, that time and that city, told primarily by the seven individuals who wrote, produced and performed it. It was a calculated and painstaking endeavour to produce sure-fire hits - whatever it took. The film follows Debbie Harry and the rest of the Blondie crew as they head into the studio to record their game-changing album with producer Mike Chapman. It also features commentary from Harry herself about writing music, the media's focus on her appearance and lyrically inspirational ex-boyfriends.
