It is January 20, 1919. Benito Pérez Galdós, already disabled and near blindness, attends the inauguration of the monument in his honor in the Retiro Park in Madrid. That night, a man dies with his throat slit at the base of the monument, and the murderer is none other than Galdós' nurse, Elena.Ten years before, Galdós had been feeling lost. Aging and the gradual loss of his eyesight had affected him enormously, and Madrid seemed oppressive to him, to such an extent that he found refuge in his memories whenever he cannot escape to Santander. It was at that time that he met Elena Mideres, an impoverished young woman nicknamed "Miseria" (Misery) and took her in as her protégée. Elena's life was as Galdosian as the author's own novels. They share with each other memories of their lives, their lost loves and financial hardships, while perambulating around that omnipresent Madrid, as if walking through a stage full of horrors.
