Sonia is a high-level executive in the fashion industry who has almost no time to spend with her husband and son. Rocio, also married and with a daughter, is Sonia’s neighbour and friend. Although she has excellent professional training, she has not been lucky and has always had temporary jobs. Each of them tries to get what the other already has, believing that will make her life better. Sonia wants to find some quiet time to be with her son who she has only seen in his pajamas lately, and Rocio wants power, social recognition, and financial independence. Getting what they want is not going to be easy because staying afloat, like The Archimedes Principle, depends on two things: what they’re made of, and the “liquid”, the work world and emotional climate where they are trying to swim.
