Sangue do Meu Sangue is a 2011 Portuguese drama directed by João Canijo set in a poor housing estate on the outskirts of Lisbon, in which single mother Márcia works as a cook and shares her home with her sister Ivete and her two children — nursing student Cláudia and small-time delinquent Joca. When two devastating tragedies hit the family in the same week, Márcia discovers the darkest one herself — that Cláudia has been in an ongoing incestuous sexual relationship with her own father, the same man Márcia once knew intimately. Torn between protecting her daughter and the unbearable truth she cannot bring herself to reveal, Márcia silently sacrifices everything to shield Cláudia from the full weight of what is happening — while Ivete makes her own desperate sacrifice to save Joca — in a film critics described as a Greek tragedy set in the ruins of contemporary Portugal.
