An armed robbery is the starting point of an unpredictable story that unfolds in four different versions; one for each of the film’s characters who rival over the "Blue Queen", one of the world’s most rare diamonds.

Martha is unhappy with her life as it is at the moment, and among other issues, she has decided to give up her writing career. Along with that decision comes a need to get away from her husband and from her psychiatrist, with whom she has had more than just a doctor-patient relationship. As Martha travels through a deserted city landscape in a storm, the external world reflects something of her inner turmoil. Flashbacks are interspersed throughout the film to enhance the suspense of Martha's inner and outer journey.
