In her early forties and single, Erika lives with her overprotective and controlling mother in a hermetically sealed world of love-hate and dependency, where there is no room for men. Her sex life consists of voyeurism and masochistic self-injury. Lonely and alienated, Erika finds solace by visiting sex shops and experimenting with masochism. At a recital, she befriends Walter, a handsome young man, whom she seduces and with whom she begins an illicit affair.
