As Variety reports, she won't just star in the biopic "The Heidi Fleiss Story" but will also produce the film.
Aubrey Plaza will bring to life the notorious "Hollywood Madam" Heidi Fleiss, who got caught running an "elite" prostitution ring in the early '90s. Her clients included Hollywood stars, politicians, and other powerful figures – the scandal rocked America.

The film will capture Fleiss during the tense days before her trial: she was scrambling around Los Angeles, trying to blackmail powerful acquaintances and leverage all her connections to make the case disappear. Helping her is an ambitious young writer named Jacqueline.
Filming will begin in Los Angeles in the coming months. The project comes from production company Pinky Promise, behind memorable films like "Bird" with Barry Keoghan and "The Last Showgirl" with Pamela Anderson.
