Sin City

The players return home to their native city after many years only to find it filled to the brim with graff, crime and corruption.  At first they do what they do best and beat up the bad guys, but instead of getting better things only take a turn for the worst.  Will the characters give into despair?
  The city needs justice, but justice must be done in the open.  The characters turn into shadowy heroes, capturing (but not killing) criminals and hauling them in.  They soon start weeding out corrupt officials and promoting those few brave politicians and cops who still believe in a better way.
