The storyline kicks off in 1976, when 16-year-old Bea (played by Alicia Falcó) is swept up in the winds of change blowing across Spain, as she teams up with the women demanding the approval of the right to abortion. This act of rebellion will intertwine with an unexpected feeling when she meets Miren (played by Elena Tarrats), with whom she strikes up a very special friendship. All this will turn that summer into a decisive stage of her life.
