🍿 Lost Girls: Detailed Plot Synopsis
Shannan’s Disappearance and Mari’s Frustration
The film opens with Mari Gilbert, a struggling single mother, dealing with her strained relationship with her daughters, particularly Shannan. When Shannan goes missing after a client visit on Long Island, Mari is immediately concerned and reports her disappearance to the police. However, she faces dismissive attitudes and a lack of urgency from law enforcement due to Shannan’s work as a sex worker.

Taking Matters Into Her Own Hands
Frustrated by the police inaction, Mari takes matters into her own hands, traveling to Long Island with her other daughters, Sherre and Sarra. She confronts the community where Shannan was last seen and relentlessly pressures the police to investigate. Her persistence and outspokenness draw attention to the case but also create friction with law enforcement and the residents of the gated community.

Uncovering a Darker Truth
As the search for Shannan continues, the police inadvertently discover the remains of other missing sex workers along Ocean Parkway. This discovery suggests the presence of a serial killer, shifting the focus of the investigation and highlighting the systemic neglect of these women by society and law enforcement. Mari’s fight for justice becomes intertwined with the stories of these other victims and their families.

- IMDB reviewer: “Excellent movie. It was well acted by all involved but Amy Ryan was outstanding, and her performance brought out the quintessence of the real Mari Gilbert and her pursuit of justice for her oldest daughter Shannan.
