Anna is a divorcee, a piano teacher, and a devoted mother. She was brought up in a family which valued achievement and self-discipline above almost everything else, but what Anna has always longed for is to be more passionate and expressive, both in her music and in her life, than she seems capable of being. Then she falls in love with Leo, an artist, and in many ways the kind of wild, impulsive person Anna has always wanted to be. Their relationship is intensely sexual and it is this, ultimately, which threatens to destroy all that Anna holds dear.
