The true story of glamorous crime queens Tilly Devine and Kate Leigh, and their deadly battle to control Sydney's underworld in the 1920s.

Norman Bruhn's Razor Gang pushes the underworld to crisis point, threatening the crime empires of Kate, Tilly and Phil Jeffs. Amid public outrage, the police fight a losing battle to stop rival Razor Gangs terrorising the streets. The rival underworld bosses convene a summit to deal with Bruhn's gang, but are betrayed when Tilly takes matters into her own hands. After being rejected by Nellie and taunted by his rivals, Frank 'The Little Gunman' Green finally gets his chance to shine.

Fresh out of prison, Kate Leigh puts a bounty on the heads of Tilly's husband, Big Jim Devine, and her chief henchman, Frank Green, as payback for the murder of Greg Gaffney and the razor attack on Bruce Higgs. In a pre-emptive reprisal Tilly vows to eliminate Kate's muscle before they eliminate hers.

Meanwhile, Kate learns the truth about her son-in-law and is forced to take action that will drive her own daughter away.
