But one day, Barbie (Margot Robbie) finds that her life has begun to change - for example, her day is no longer smooth sailing, she begins to think about the meaning of death, and even her feet are no longer in perfect high heel shape - she actually fell to the ground! The successive imperfections broke the tranquility of Barbieland. Barbie, who realized the crisis of existence, was forced to go to the real world to explore the truth.
