The Lover in the Attic: A True Story (2018)

In 1920s Milwaukee, sultry and seductive Dolly feels trapped in her marriage to wealthy but boorish Fred. She obtains a young "love slave" named Otto and hides him away in her attic for years. But when Otto shoots Fred dead, Dolly tries to pass it off as a robbery gone awry. Chief Detective Herman doesn't quite believe this and tenaciously pursues the case. Dolly moves to Los Angeles, where she uses her ill-gotten insurance money to live the high life among the Hollywood fast set. At one of her parties, she meets Herman, a prominent Los Angeles defense attorney who is quickly smitten with the seductive newcomer. After a torrid affair, he proposes to her and she ecstatically accepts. All along, she keeps Otto a slave and a closely-kept secret in her life. But her seductive wiles could ultimately backfire on her, as jealous Otto realizes that he would rather face the full penalty of the law than one more day of her manipulation and betrayal.
