"The Subterraneans" shows us what the largest independent cultural event of recent years is, how it came about, and how it's organized: the Independent and Alternative Book Fair (F.L.I.A.). Self-managed, always open, free, and accessible to all, the F.L.I.A. is a channel for free expression that continues to grow and expand throughout Argentina and the world. Narrated by its protagonists and accompanied by a dynamic cascade of images, Tomás Larrinaga ("El Gauchito Gil, La Sangre Inocente") captures the essence of this phenomenon.
