Julieta is a teacher of 55. She writes a long letter to her daughter, Antia, explaining the secrets she has kept from her over the last 30 years. But when she finishes her confession, she doesn't know where to post it, because they have been estranged since Antia left her at the age of 18. It's based on three short stories by the Nobel Prize-winning writer Alice Munro which follow the same character at different stages of her life.
