The film follows her encounters, which reveal a person in crisis. The deeper, more honest, and more complex her encounters become, the more she fulfills the characteristics she is accused of. At the same time, the story also follows her pregnancy, and the closer she gets to giving birth, the closer she gets to a new understanding, which serves as a contrast to the crisis she is experiencing at work.
