Twelve months after her sister Anahita's death, Mitra Jahani returns to her parents' home in New Jersey to observe the Iranian custom of "The One Year." Ana is always in Mitra's heart, though they chose very different paths. While Ana bowed to their father's demands and married, Mitra rebelled and was banished. Caught in the middle is their mother, Shireen, torn between her love for her surviving daughter and her loyalty to her husband. Yet his callousness has compelled her to rethink her own submission. And when Mitra is forced to confront hard truths about her sister's life, mother and daughter reach a new understanding - and forge an unexpected path forward.
