When 24-year-old Shannan Gilbert mysteriously disappears one night, her mother Mari played by Amy Ryan, embarks on a dark journey that finds her face to face with hard truths about her daughter, herself, and police bias.

Determined to find her daughter at all costs, Mari Gilbert retraces Shannan’s last known steps, driving her own investigation to an insular gated community near the desolate outer banks of Long Island. Her discoveries force law enforcement and the media to uncover more than a dozen unsolved murders of sex workers.

Director Liz Garbus says that this film is about believing women: “Lost Girls tells the story of families whose daughters have gone missing. These families are told there’s nothing the police can do and the disappearances are virtually ignored.”

Inspired by Robert Kolker’s best-selling nonfiction book of the same name and produced by Archer Gray’s Anne Carey. Lost Girls is directed by two-time Academy Award nominee Liz Garbus (The Fourth Estate; What Happened, Miss Simone) and stars Irish Tony -and Golden Globe winner Gabriel Byrne.

Lost Girls releases today on Netflix, watch the trailer below.
