The Mapocho River's reputation is challenged by three friends when they decide to descend it on a kayak. But how does a kayak behave on this river that nobody sails and goes through the heart of Santiago? Going beyond the Mapocho River's dirty image, this adventure takes us to a place where it's possible to look at the Chilean capital city from a unique perspective. It is not that people love cities because they are beautiful; cities are beautiful when people love them.
