Beneath this façade she is a self-taught intellectual, devoted to arthouse Japanese cinema and has a cat named after Tolstoy. Meanwhile, several floors up, twelve-year-old Paloma has also learned to conceal her gifts. The precocious and lonely daughter of pampered parents, Paloma is convinced that life is meaningless and plans to commit suicide on her next birthday. But the arrival of a new charismatic resident will bring dramatic change to number 7, Rue de Grenelle, altering the course of both their lives forever.
