Karma Knox was the experimenter of the Knox sisters. While down to earth Emma was studying and working, first as a cop, then as a private eye, Karma played. She modeled, dabbled with BDSM and married a pilot who let her play housewife in the suburbs. Until one day she went shopping with her sister and woke up in a dungeon naked, with a steel collar on her neck, chained to a wall in a bare cell. Then life got interesting again.
