We visit the Las Patronas women 30 years on from when the young Romero Vazquez sisters first threw a loaf of bread onto the infamously dangerous La Bestia train. A train meant only for cargo, but which has become a dangerous mode of transport for more than 400,000 migrants every year. It begins from near the border of Guatemala, and along its 2000 mile journey migrants from Guatemala, Honduras, El Salvador, Nicaragua and Mexico itself cling to its roof, heading north to America. Norma Romero guides us through the last 30 years since her and her sister first made the decision to help the passing migrants.
