Storyline:  In 1711, alchemists gain immortality but must kill each other until one remains. Regretting this, they destroy the elixir—except Slizard Quates, who starts hunting them. By 1930 Manhattan, Quates recreates the elixir but loses it, and it’s mistaken for alcohol, consumed by thieves Isaac and Miria, Mafia families Gandor and Camorra, sparking chaos in the criminal underworld.
