Communist soldiers accidentally unleash the part-vampire servant of Dracula, as well as his vampire dog, during excavations in Romania. Together, they set out for America to find the last living direct descendant of the great Count. Meanwhile, said descendant, unaware of his true heritage, goes on vacation with his family and their dogs, not knowing they are in great danger. Fortunately, a vampire hunter is also on the case and is tracking down the servant and his dog, as well as the descendant, in order to destroy the former and protect the latter.
