On the wedding day, the bride disappeared into the secret room, with a strange man's bodily fluids remaining on her dress.
A DNA comparison rules out the groom, but discovers an illegitimate daughter who has never been seen.
The murderer is playing a game with us: he kills one person at the wedding scene, but makes another person disappear out of thin air.
And this is just the beginning of revenge.
