The hunters escape by firing a cannon at the door—substituting steam pressure for gunpowder—and come to the ball in disguise, where, although exposed by their reflections in a huge mirror, they are able to grab Sarah and escape. Fleeing in a horse-drawn sleigh, Abronsius and Alfred are unaware that it is too late for Sarah, who has already been transformed into a vampire. She awakens in mid-flight as a vampire and bites Alfred, thus allowing vampires to be released into the world.
