Sam, Prune and Alice love gatecrashing parties. When they manage to procure invitations to the mysterious Medici Night, they think they've really scored. They're quickly brought down to earth when they discover that their hosts are vampires and all the guests are there to act as supper. If getting into this party was very difficult, getting away from it will prove impossible. The three friends are ready to do whatever it takes to escape, dragging along in their mad rush Edouard, a hopeless millstone, Krinine, dentist to the stars, and Jessica, a gangster's wife with the IQ of a gnat.
