Nina Negri stages the invisible barriers posed by social norms, especially for women. She draws inspiration from John Cassavetes' film A Woman Under the Influence, which examines the descent into madness of a manipulated woman. She doubles the drama with two krump dancers and the presence of children to reveal the mechanisms of violence and imprisonment.

On the stage of Sous influence, enclosed in a translucent and mobile device, Mabel and Nick confront each other, irresistibly in love yet at odds. The couple is accompanied by two krump dancers, an urban dance form born in Los Angeles in the 2000s to exorcise social violence. Around them, children watch and dance, resisting the normative power that progressively imprisons Mabel.

Nina Negri observes Mabel, her freedom, her mad love, the beauty of her fire. She looks at this woman who exposes herself, to society, to others, to herself, to her strengths and fears. The distraught Mabel is constantly pulled back, reined in, constricted by the model of the couple and social expectations, until she is institutionalised. Norms undermine her, hold her back, but what are they, where do they come from? Her vital strength opposes them with song, free movement, life, the choice to love.

Continuing her research into film and stage editing, Nina Negri draws her inspiration this time from the great American filmmaker, John Cassavetes. She retains the way in which the filmmaker manages to describe the conscious and unconscious impulses of his characters through a floating frame and often surprising, even paradoxical editing. By transposing this with the means of theatre, she exposes the intangible boundary between norm and madness. Urban dance, theatre and cinema thus make it possible to perceive the barriers with which women are confronted, even today.
