Lucrecia, a young, poor and illiterate girl in sixteenth century Madrid, living in the court of Filipe II, has terrible visions announcing the disastrous end of the Spanish monarchy, including naval battles and invasions of heretics. Fascinated by her predictions, priests and nobles try to exploit her, forming around her a dark congregation. Rigorously documented and written from the strict fidelity to historic events, Ru'a Lucrecia recreates a time not so different to our own, breaking down the boundaries between reality and fiction.
