In 1998 in Laramie, Wyoming, United States, Matthew Shepard, a twenty-two-year-old student, is attacked by two peers in an act of a homophobic nature. Dying, he is transported to the hospital, where he dies a few days later, shaking public opinion overseas and beyond. Starting from a true crime story that really happened, director Martina Arrigoni transposes to the big screen the rehearsals of the play "The Seed of Violence - The Laramie Project" by Moisés Kaufman and the Tectonic Theatre Project directed by Ferdinando Bruni and Francesco Frongia, produced by Teatro Elfo Puccini, where eight actors bring about sixty characters to the stage, bringing to life the words and thoughts of the Laramie community as they question their own responsibility for what happened to the boy, in a rehearsal journey that evolves to the present day in Milan.
