Jenny (Billie Piper of DR WHO) and several other college students are contacted by a housing agency that there are rooms available at an old mansion. As strange events start to happen and people begin to die they eventually realize that they've been summoned to this place for a specific purpose, which isn't all that surprising.
The sets are suitably creepy and enough is going on so that the story doesn't get boring, although the scripts borrows from both William Castle's HOUSE ON HAUNTED HILL and THIRTEEN GHOSTS.
