The year is 1932 in the south side of Chicago. By day, small-time thugs lurk through the city streets hoping to make a big score. By night, criminals are on the hunt for unsuspected victims. It's a never-ending war. After the city is relieved of Big Boy Caprice, another crime boss named Ominous resurfaces from out of hiding with his men. Ominous discovers that a local night club in town holds the darkest secrets in the city to help get him on top. When multiple men are gunned down in a warehouse, Dick Tracy and his ambitious partner Joe Buzzer are on the case. They follow clues and pick up leads throughout the city. Ominous relies on his hatchet men Clover, Torpedo, Jersey, Pinstripe, and Spats, to keep them occupied. Tracy and Buzzer will have to work well after hours to have any chance at catching their man.
