It's 1907 Los Angeles. Mischievous socialite Anna Blanc could match wits with Sherlock Holmes, but in her world women are not allowed to hunt criminals. Determined to break free of the era's rigid social roles, she buys off the chaperone assigned by her domineering father and, using an alias, takes a job as a police matron with the Los Angeles Police Department. There she discovers a string of brothel murders, which the cops are covering up. Seizing her one chance to solve a crime, she takes on the investigation herself.
If the police find out, she'll get fired; if her father finds out, he'll disown her; and if her fiancé finds out, he'll cancel the wedding.
Anna must choose--either hunt the villain and risk losing her father, fiancé, and wealth, or abandon her dream and leave the killer on the loose.
