Recording of the play of the same name by Cacá Rosset and Grupo Ornitorrinco, based on the play by Alfred Jarry. The play tells the story of a certain Pére Ubu, who, in order to become powerful, takes the crown off the King of Poland, killing the whole royal family. His conscience hurts, but nevertheless war is declared, mobilising all of Ubu's deviousness: betrayal, dishonesty, greed.
