It's Friday night in Asunción, Paraguay and the temperature is sweltering. VÑctor, a 17-year-old wheelbarrow delivery boy, dreams of becoming famous and covets a fancy cellular phone in the infamous Mercado 4. He's offered a chance to deliver seven boxes with unknown contents in exchange for a quick US$100. But what sounds like an easy job soon gets complicated. Something in the boxes is highly coveted and VÑctor and his pursuers quickly find themselves caught up in a crime they know nothing about.
