Drama Christinas vow is based on fragments from the life of Christina Doctare, Swedish doctor, humanitarian, and a published author, who also held positions in relation to health and social welfare in Sweden. To a wider public, Christina is known for her engagements during the Cyprus war in 1974 and war in Balkans in 1992.

During the war in Cyprus she was the first Swedish woman to be deployed as a military doctor with the UN battalion, while during the war in the Balkans she was a lead on a physical and psychological rehabilitation project under the aegis of the World Health Organization (WHO). She was one of the first people to report on systematic rape during the war in Bosnia and Herzegovina. For a while, as Swedish representative, she also worked at the European Committee against torture.

Following the decision of the Nobel Committee to award writer P. Handke, denier of crimes committed over Bosniaks, Croats and Albanian Kosovars with a Prize for Literature, Christina got actively involved with protests against this shameful decision. She was a key speaker at the Stockholm protest which took place on 10th of December 2019. On this occasion, Christina Doctare returned the Nobel Peace Prize medal she was awarded in 1988, for being one of the UN troops.
