The demon gives them an elixir of immortality and the method of ending their existence by "devouring" one another. Soon after, one among them begins to devour his companions. Realizing the danger posed by staying together, they scatter across the globe. Centuries later in 1930's America, a certain federal investigator tries his best to combat the rise of organized crime during Prohibition, send a particularly infuriating terrorist to Alcatraz, and catch an outrageous thief duo. Meanwhile, the transcontinental train, the Flying Pussyfoot, begins its trail of blood across the country. In 2002, a small group of the original Advenna Avis alchemists are on a journey to find the rest of their fellow immortals. However, there is one companion they did not expect to meet again.
