Fiftysomething Julieta writes a long letter to her daughter Antia, trying to explain all the things she has kept secret in the last thirty years, since Antia was conceived. But when she finishes the confessional, she doesn't know where to send it. Twelve years ago, her daughter left home at eighteen abandoning her mother, who's unsuccessfully searched for her everywhere - only to realize that Antia was a total stranger to her.
