It is August, 1864. America is in the midst of its Civil War. That is not the only war being waged. Moralan, the Demon Lord of the Underworld has chosen this time to possess mankind. Standing in his way are THE SLAYERS. Led by Alexander Masterson, the Slayers are five men and one woman who have extraordinary powers. The Slayers have fought Moralan in the Demonic Wars for ten thousand years. A dark, storm evening, Alexander's wife Rosario is giving birth to their daughter. It is a painful birth which ultimately takes the life of Rosario. With the birth of his daughter, Senka, and as demonic forces close in, Alexander decides it is time for the Slayers to regroup and head west to continue their battle against evil there. As the demonic forces close in, the Slayers make their exit to California.
The birth of Alexander's baby girl, Senka, has telepathically alerted the Demon Lord of the Underground of their location. Claudia, Alexander's mother-in-law, pleads with Alex and the Slayers to leave to protect Senka. Claudia relates the story of how she and Moralan met and how he seduced her. The Slayers want to fight; however, Claudia convinces them to leave to continue their fight against the Underworld at another place. The Slayers head west as Claudia ventures out for her showdown with Moralan to buy time for the Slayers to make their escape.
Alexander and his Slayers have reached Bodie, California and much like the Earps in Tombstone have set themselves up as the town lawmen in Bodie. Alexander is the Territorial Marshall while Robert, Archie, Lowell, Joshua, Nikita serve as his deputies. Senka continues to grow and learn fighting skills from each of the Slayers. Life is quiet and normal, with no sign of Moralan and his demons. The only threat are the criminals raising havoc in their county.
