The Americas with Simon Reeve

The explorer travels from Texas to southern Mexico, meeting a woman who risks her life to take supplies to migrants stranded on the Mexican side of the border in Reynosa, one of the country's most violent cities, which is dominated by a powerful criminal organisation. He also ventures into the rainforest to explore the Maya city of Yaxchilan, and meets the modern-day descendants of this civilisation, who are increasingly marginalised and treated as second-class citizens
