Sangue na Guelra is about PROJECT 12/15 created by the Intercultural School of Amadora in a suburb of Lisbon to fight the dropout of sixty young people between 12 and 15 years, divided into four classes. The documentary was shot between January and June 2013 and without sentimentality or sensationalism shows the journey of these young people in the school which gives them a last chance to acquire a minimum of basic knowledge. Through the film, we discover the relationship and the conflicts they have with each other and with their teachers. The humanistic aspect has been privileged in a documentary that seeks to engage the viewer directly into reality through aesthetics without artifice.
