In the year 22xx Dracula has conquered the world. The Pope, with no other good options left, of course has his soul transferred into a robotic shell (codenamed F.A.T.H.R.) and sent back in time to the year 18xx, before Dracula was able to truly amass his forces.

Once there he meets up with a ye olde prototype robot that the Vatican had sent to try to stop Dracula way back in the day, S.O.N.

Together the cold, emotionless monster-killing machine S.O.N. and the desperate future-pope F.A.T.H.R., armed with only their electro-beams,  must make the very walls of Dracula's unholy castle run red with the blood of his minions.
