"It's 1935, and ever since the big crash and her father's subsequent suicide, Henrietta Von Harmon has been left with the job of caring for her antagonistic mother and seven younger siblings. In desperation, Henrietta finally agrees to take a job as a taxi dancer at a local dance hall. Just as she's beginning to enjoy herself, however, the floor matron suddenly turns up dead. When the aloof Inspector Howard appears on the scene to investigate, he persuades Henrietta to go undercover for him, plunging even deeper into Chicago's gritty underworld."--
