During 2015 and 2016 the scientist Fernando Ventura began to manipulate the DNA of some people to investigate their traumas and the possibility of changing the genetic sequences of them. The genetic manipulation led to a resounding police case and the tragic end of the scientist. Some of the people whose DNA was manipulated are the son of a drug trafficker, a trans boy, an accident survivor and an international stripper. They reconstruct their stories, with their testimonies and personal files, along with those of the experiment of which they were part.—Baltazar Tokman
