In one of the last scenes, Uruguayan director Mario Handler explains why he visited former comrades, victims, prisoners and an executioner of the dictatorial regime (1973-1986) in his motherland and registered their stories in Tell Mario Not to Come Back. Handler finds he owes it "to all those who have suffered, while I did not do anything against the dictatorship or stand up for my people." The fact was that Handler fled to Venezuela at an early stage, where he continued making films, but intentionally not a single one about Uruguay. From 2004 to 2007, Handler traced a number of protagonists who told him what life looked like during the thirteen-year dictatorship. Intellectuals, like two writers, a journalist, a filmmaker, a researcher and an accountant describe how they were imprisoned and tortured and how it influenced their lives. For the first time ever, an Uruguayan military torturer speaks out - the convicted former Chief of Intelligence also discuss those days with Handler, revealing the training on interrogation techniques they received from foreign Intelligence services, i.e. West Germany and Israel. The interviews are alternated with clips from Handler's earlier films and from the general Uruguayan news archive.
