The Haunting ending explained (spoilers)

[bernice]

Luke gets his head ripped off by the lions head in the fireplace. Nell is the great-granddaughter (or great-great-granddaughter, whichever) of Hugh Crane (the owner of the house who killed the children and haunts the house). Nell, the doctor (Liam Neeson) and Theo (Catherine Zeta-Jones) lead Crane to a door where a bunch of spirits trap him. The souls of all the children can finally rest in peace. Nell realizes she has to stay at the house to protect the souls of the children and then dies. Theo and the doc leave the house.
