James has mysteriously inherited a family mansion that he never knew existed.  It's a beautiful, if run down, old place, just outside of the Taipei suburbs.  The commute is going to be a little tricky, but for a house like this, it's worth it.  With a new house and a good job, James is ready to take the long walk down the aisle, and asks his long time girlfriend, Yo,  to marry him.  Newly engaged, Yo moves in with him and she begins to put the house in order.  That's only the beginning of the horror James is going to find himself surrounded by!

Not even married yet, Yo begins to invite her friends over all the time.   What's worse — her friends start appearing in the house out of nowhere, right around midnight each night. They don't know how they got there, and they don't know what they're doing. They just show up out of thin air.   If that's not enough to drive poor James crazy, soon enough they start showing up dead!  Each one of them has the appearance of being hanged, yet no rope is ever found.  The only thing James does find, are little footprints throughout the house, and a locked attic door.

With nothing better to do than pry into her soon-to-be husband's private affairs, Yo digs into James' family history. She finds out his ancestors were into hsiao guei, the practice of worshipping the ghosts of dead babies.  As part of the ritual,  the family would keep a corral of stillborn fetuses in jars, feeding each with the blood of various family members.  Creepy to be sure, but what does that have to do with the fact that James doesn't remember any of it, and that his only living relative is an aunt in a mental hospital?  Why is everybody being hanged, and what, if anything, do the ghost babies have to do with it? 

Plenty.

Yo's on the case, and she'll stop at nothing to bring the Ghost Babies to their final rest. But will the Ghost Babies let her and James rest?
