In a quiet countryside farmhouse, Britain's vampires gather for their once-every-fifty-years meeting. Others will be joining them too; Sebastian Crockett, an unwitting Essex boy who thinks he's on a promise with sexy cougar Vanessa; and a detachment of Special Forces vampire killers who have bitten off more than they can chew. This is certainly going to be a night to remember... and for some of them it will be their last.
