Frank Drake and Rachel van Helsing are caught up in the chaos until Harold H. Harold arrives for a timely rescue. After regrouping with Quincy Harker, they then track Doctor Sun down to his laboratory lair. Rachel kills man-servant Juno, but Doctor Sun escapes. They realize that the only way to stop Doctor Sun is by resurrecting their greatest enemy - Dracula!
