Los Angeles, 1946. The city is booming in the post-war era, but the glittering underground jazz and cabaret scene is firmly under the thumb of a shadowy, ruthless mob syndicate. A charismatic, fiercely independent nightclub singer finds her world shattered when a prominent mob boss is found dead in her dressing room. Knowing the corrupt LAPD has already framed her as the perfect scapegoat, she goes on the run within the confines of the city limits. To clear her name and protect her found family of musicians, she must play a deadly game of chess involving rival gangsters, Hollywood elites, and dirty politicians, using her intellect and insider knowledge of the clubs to unravel a conspiracy that reaches the mayor's office.
