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.

Furious over Tilly's decision to kill Norman Bruhn, Kate sparks an all-out war by recruiting Tilly's prostitutes to sell cocaine. Snowy Cutmore returns to Melbourne for a fateful showdown with crime boss Squizzy Taylor. Fresh from his first kill, Frank 'The Little Gunman' Green wins the ultimate prize — Nellie Cameron. But can he keep her?

Phil Jeffs faces the hangman's noose for a scandalous crime that has all of Razorhurst guessing.

The rivalry between Kate Leigh and Phil Jeffs reaches boiling point, leading to a legendary street battle between their rival gangs. Jeffs is determined to put Kate and Tilly out of business by poisoning their cocaine supply and slashing their workers. The police create Australia's first drug squad to fight the deadly cocaine epidemic, and Kate starts an affair with a sexy young gangster, angering her faithful lieutenant Wally.

Black Aggie strikes up a romance with Greg “the Gunman” Gaffney and gives-up prostitution. But she’s still dirty on Nellie for putting her out of work, so she fronts her with a cut-throat razor. Frank Green intervenes and gives Aggie thrice as many cuts and bruises than she started out with.

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.
