Based on true events of the late 60s in Italy, poet, playwright and myrmecologist Aldo Braibanti is prosecuted and sentenced to prison for the love he shares with his barely-of-age pupil and friend, Ettore. Amidst a chorus of voices of accusers, supporters and a largely hypocritical public, a single committed journalist takes on the task of piecing together the truth, between secrecy and desire, facing suspicion and censorship in the process.

Milan, Italy, 1967. Santo Russo, a boy of Calabrian origin, arrives north with his parents and younger brother to find better living conditions. Due to an absurd misunderstanding and his father's contempt, Santo ends up in prison, where he gets a “true education.” In 1978, he and his friends Slim and Mario embark on a 15-year criminal career, a successful and ruthless spiral of robberies, kidnappings, murders and heroin smuggling.
