Su A, before passing away, makes an unbelievable promise to her husband, U Jin, to return one year later on a rainy day. Miraculously, she keeps the promise and reappears before her husband and son, but all her memories have disappeared. Tragically, the relief at their reunion is short-lived because it turns out that Su A has to leave her family once again.
