Melody considers herself lucky that she found love once in her lifetime. Her blissful life, however, abruptly came to an end; all hope of knowing love disappeared the day she lost Jack. She's still alive, but she can't move on from that loss, and she knows she'll never love another man the way she loved him. It's just not possible. But Jack, even though he's dead, knows that Melody's heart is big enough to give love a second chance, and he doesn't want her to face life alone. The challenge lies in helping her meet just the right man. Uncertain whether he's an angel or a ghost, Jack finds himself in a new and strange body, searching for a man to make Melody feel alive once more while not letting her fall in love with him again. Such conflicting emotions - and to top it off, he only has until Christmas Eve at midnight to help Melody fall in love... with someone else.
