The action in this opera takes place in a house filled with secrets, from childhood memories to silent torture. The oppressive walls hide horrific stories of the sinister, brutal bonds of the current inhabitants, the Ashtons.

Everything is corrupt, their souls are poisoned with hatred and power, nobody is free of this macabre game that bodes a fearful ending in which Lucia is the bargaining chip. Moral and physical decay pervades the scene and its characters.

The first gloomy, menacing chords of the opera are a presage of the story we are about to witness. Lucia bears the burden of a death that she cannot overcome. In her nightmares, she is visited by her mother's ghost.

Her brother, mindful only of his own interests and violent outbursts, ignores Lucia’s grief and "snatches" her from her mourning. He forces her to dress as a bride and consummate the wedding, believing that this is the only way to save her.

Lucia can only utter the one name that weighs in her mind, Edgardo, the window through which she can see the light. A rushed wedding and an improvised conviction.

Lucia is not mad and her mind is not weak. She is forced to react and speaks from hell itself after being pushed to the edge of the abyss.
