Marc Deville is a highly celebrated author of erotic literature who lives a completely isolated personal life. Desensitized by a severe addiction to pornography, Marc is psychologically incapable of physical intimacy unless a camera separates him from the real world. His rigid boundaries are pushed when he meets Justine, an enigmatic nurse who is trapped in an increasingly volatile and abusive marriage to Eric, a prominent theater director. Estranged from her husband due to her dark, unfulfilled fetish for erotic asphyxiation and an obsession with death, Justine finds an unexpected kindred spirit in the detached author. Seeking an escape from her suffocating domestic life, Justine embarks on a dangerous extramarital affair with Marc. As the cheating wife and the isolated writer cross deep psychological boundaries together, their secret relationship becomes a raw, explicit exploration of trauma, control, and the desperate search for genuine intimacy.
