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. 　　译文(2): 埃尔南和他的妹妹黛西是玻利维亚的青少年，他们正在 Cochabamba 上高中，梦想着组建一个乐队。在购买一套鼓的欲望驱使下，埃尔南同意非法携带两公斤可卡因越境到阿根廷。在他被边境警察抓住后，他被送到圣塞巴斯蒂安监狱，一个几乎没有人员的露天设施，在那里犯人制定大部分的规则。
