Details The Hollywood Reporter, "The story is set against the Dust Bowl of the 1930s, when 'black blizzards' obscured the Midwest and prairies. The plot sees a G-Man investigating the disappearances of entire families from small towns during these storms, uncovering the existence of an army of vampires that are using them as cover to ravage the countryside. The agent is forced to team up with remnants of Al Capone’s gang to save Chicago when the vampires turn their attention to the Windy City.
