It begins as a bedtime story…
What follows is an epic battle between good and evil. An artifact from Noah’s ark sets the stage for this global World War 2 adventure, which introduces the world to Sam Dark. Sam Dark is a man born into privilege, as the son of the richest man in the world. Sam over indulges in adventure, drinking, and women when a family tragedy forces him to reevaluate himself, while the man who orchestrated the event joins forces with the Nazis and still seeks to inflict damage on Sam, Sam's family, Sam's friends, and the entire world.
However, Sam Dark rises from the ashes of tragedy and will act against those who want to do harm.
