Question: What does Terrori tell Pepito to have as his last drink? Title: Vampiros en La Habana! Movie plot: Joseph Amadeus von Dracula, known as Pepito to his friends, is a trumpet player in 1930s Havana who spends his time away from the bandstand dabbling in quasi-terrorist plots to overthrow the Cuban government of dictator, Gerardo Machado. He is unaware that he is really a vampire, and that his uncle, Werner Amadeus von Dracula, the son of Count Dracula, has been using him as a test subject for a formula that negates the usually fatal effects of sunlight. A Chicago-based crime syndicate and a group of vampires with members from several countries in Europe have both learned of the formula and wish to possess it for different reasonsthe Chicago group to suppress it and thus maintain their monopoly on indoor, artificial beach resorts, and the Europeans to market it as "Vampisol." When Pepito learns of his true heritage (and his uncle's wish to give the formula away to vampires everywhere) he becomes the target of a multi-pronged manhunt, leading all parties involved on a wild chase through some of the seediest neighborhoods of Havana. At the film's climax, Pepito and his girlfriend find themselves cornered by the Chicago vampire cartel, led by vampire mobster Johnny Terrori. He tells Pepito to have some O positive blood as his last drink, the blood type which vampires consider to be the most delicious.

Both groups believe that they are going to make a...???
