In the uncertain era of 17XX, Dracula descends on the city of Goidel and abducts Lydia, the daughter of the city's elder. Desperate for help, the elder enlists a valiant knight named Sonnie to enter Dracula's fortress and bring Lydia home. The castle is filled with hostile creatures and dangers at every turn, and Sonnie—joined by a second playable character—must fight through them all to reach the count.
