Determined to escape poverty, Bonnelyn Parker secretly takes a night job in a 1927 speakeasy while maintaining her wholesome-girl identity by day, an endeavor that introduces her to convicted felon Clyde Barrow, who entices her to become his partner in crime.

Summer, 1927. Bonnelyn Parker is more likely to belt out a church hymn than sling drinks at an illicit juice joint. She plans to overcome her family's poverty, provide for herself, and maybe someday marry her boyfriend, Roy Thornton. When financial woes jeopardize her ambitions, Bonnelyn finds salvation in an unlikely place: Dallas's newest speakeasy, Doc's. When Roy discovers her secret life as a moll, he embraces it-- perhaps too much. But her life is headed for a crash. Bonnie Parker is about to meet Clyde Barrow.
