Vampire Party(2008)

This party is going to suck.

Best friends and hardcore partiers Sam, Alice and Prune have scored invitations to 'Medici Night', the legendary VIP bash held every year at a remote castle. But when they discover that this wild party is being thrown by an elite race of blood-crazed vampires, they'll have to stake, stab, slice, bludgeon and blast their way out of a soiree where the hosts are thirsty and the bar is now open.
