Which Side Do You Choose? Welcome to Chicago! Since the introduction of the 1920 prohibition laws that forbid the manufacture, sale or transportation of alcohol, this city has become the center of organized crime. Now, all alcohol consumption is controlled by the Mafia, the city is teeming with illicit breweries, bars, nightclubs, casinos and brothels. In 1928, the dreaded Hank O?Neil rules over most of the city but a few areas are still under the control of the authorities. Now another big shot, Don Falcone, even more ambitious, cruel, and ruthless than O?Neil, has arrived on the scene and is muscling in. A special police unit has been set up to meet this threat and to stop the Mafia at all costs. Their aim is to regain control of the city and to free Chicago from the grip of the underworld.
