‘We went to the dark side’: horror film shows reality of Mexico’s migrant trail

Mystical realism conveys real-life stories of brutal cartel violence in Fernanda Valadez's chilling directorial debut

Two teenage boys wave goodbye to their mothers across a field in rural Mexico, leaving home in search of the American dream. The opening moments of the Mexican film-maker Fernanda Valadez's Identifying Features, available to stream from this week, reflects scenes played out every day across Mexico and Central America, as men, women and children journey north in search of safety and job opportunities.

Valadez, 39, starts her directorial debut film in her home state of Guanajuato - a picturesque, once tranquil state in the centre of the country. In recent years Guanajuato has fallen victim to the evolving geography and relentless nature of Mexico's humanitarian crisis; it is now one of the most dangerous places in the country for those who live there and for people travelling through on the migrant trail.
