This week Dan Snow, Anita Rani and Ade Adepitan are in the crowded and congested Mexico City, uncovering the hidden systems and armies of people that help run this sprawling megalopolis of over 22 million people.

Anita discovers how they are trying to stop the city from drowning in its own waste, while Ade heads to the edge of the sprawl to find out about the daily struggle for clean, affordable drinking water. Dan reveals how you build a skyscraper in an earthquake zone and learns the hard way that Mexican street food can be hot.
