Cocaine Prison（2019）

Hernan and his sister Deisy are Bolivian teenagers going to high school in Cochabamba with dreams of starting a band. Driven by the desire to buy a drum kit, Hernan agrees to illegally carry two kilograms of cocaine across the border to Argentina. After he's caught by border police, he's sent to San Sebastian prison, a scarcely staffed open-air facility where the prisoners make most of the rules.
