No woman in Hell's Kitchen is as tough as Battle Annie. Known as the sweetheart of the notorious Gopher gang, Annie makes a living as a brick hurler and brawler, always working for the highest bidder during the railroad strikes of the 1890s. An orphaned girl named Cora endures the brutal life of a guttersnipe on the street. Her only hope for survival is serving as Annie's helper during the brawls.
After an encounter with the famous socialist Eugene Debs, Annie has second thoughts about hurling bricks against striking workers. Those second thoughts lead to trouble when a rival comes for Annie's throne and a powerful railroad executive wants more from Annie than he's paid for. When she's falsely accused of murder, Annie flees New York with Cora in tow. Hiding in plain sight, they pass themselves off as a respectable milliner and her orphaned niece. But eventually Annie's past catches up to her and she must run again or face the electric chair. Cora will need to shed the trappings of her new life in order to save Annie, but Hell's Kitchen is in her blood. Without anyone around to guide her, will she abandon Annie and return to a desperate life in the rookery where she was once a guttersnipe? And will Annie be executed for a crime she didn't commit?
