11 Underground

In 1984, the hard-fought protest of 11 Spanish mercury miners made the national news as they barricaded themselves hundreds of meters below ground in a mining shaft for 11 days and 11 nights in protest of poor working conditions and pay. 35 years on, the mine is closed for good; the world in Almadén has changed, but the problems kept growing. Can the spirit of the miners’ strike rise once more and help bring hope and social justice to a community isolated in their fate?
