Elena, a young Brazilian woman, travels to New York in pursuit of her dream of becoming an actress, leaving behind her seven-year-old sister Petra. Two decades later Petra also becomes an actress and sets off for New York in search of Elena, of whom she has only small clues: family videos, press cuttings and a diary. At any moment Petra expects to find Elena walking down the street in a silk blouse. Little by little the features of the two sisters blur; we can no longer tell one from the other.
