As fog descends, the last remaining members of the murderous Tomb family return to the family mansion to receive information about their inheritance from Crayle, their scheming lawyer. The last time the family visited only two people survived! In the cob-webby corridors things (and people) are seldom what they seem as, with poison in every decanter and mysterious disappearances into secret passageways, hosts and guests alike join the increasing number of bodies in the cellar. A super murder mystery spoof to keep the audience guessing 'who dun it'!
