Located on the Mexican/US border, this is the only public hospital in a city of one million people, at the epicentre of a drug war that has already claimed more than 50,000 lives across the country. The hospital is also on the front line as a provider of emergency care for those caught up in the violence. The nurses treat many patients with minor injuries whilst dealing with a constant stream of traumas and a lack of resources. For two weeks, relying only on basic technology and equipment, Maria swaps her hospital in Preston to work alongside auxiliary nurse Pablo Vasquez and deals with a staggering number of patients who have either been stabbed or shot.
