1920s Milwaukee: Frustrated within her marriage to the pompous Fred, Dolly, a woman of seductive charm, conceals her devoted "servant" Otto in her loft for years. However, when Otto takes Fred's life, Dolly attempts to frame it as a botched robbery, which doesn't sit well with Chief Detective Herman, who relentlessly pursues the case.
Escaping to glamorous Los Angeles, she spends her stolen insurance fortune on living lavishly among Hollywood's fast crowd. At one of her extravagant parties, she encounters Herman, a renowned LA defense attorney, who is captivated by Dolly's allure. After a passionate affair, he proposes, which she gleefully accepts.
Intriguingly, Otto remains her secret slave throughout their relationship. However, as jealousy takes over, Otto realizes he would rather face the law's full wrath than endure another day of Dolly's manipulation and deceit. The siren song of seduction might prove to be Dolly's undoing in this gripping tale of love, betrayal, and retribution.
