Arrietty survived a bridge collapse but was in a coma for 4 weeks, when we wakes up she thinks it's Christmas in 2020, nearly 10 years earlier. She has to come to the shock of being 30 dealing with what she has done with her life in the ten years since then. But while recovering in the hospital , she keeps receiving gifts from a strange man. He seems concerned for her...almost as if he cared for her. With so much happening, Arrietty has to reconnect with those she remembers and face those who she doesn't...including significant others.
