In her working life as a prison psychologist, Lilian deals with criminals who have experienced a lot. She herself is equally full of secrets, as it seems, a woman strongly led by her perception and intellect while keeping others and their emotions at a distance. A woman who does not say much and yet takes decisive actions, usually in a trench coat, quite motionless. When her estranged father dies, she returns home to Bulgaria; in the flat he has left her together with his debts, she encounters an amazing snake and her own extreme lust, which has long been held in check by a celibacy pact. The knots and ties come undone during the act of shibari, and liberation begins.
