Amy Ryan is to star in the Netflix film adaptation of Robert Kolker's non-fiction book "Lost Girls."

The project will mark documentarian Liz Garbus' narrative feature debut.

"The story, both a true-crime story and a strong character piece, follows Mari Gilbert as she relentlessly drives law enforcement agents to search for her missing daughter and in the process sheds light on a wave of unsolved murders of young female sex workers on the South Shore barrier islands of Long Island," a news release said.

Garbus' films include "The Farm: Angola," "USA," "Ghosts of Abu Ghraib," "Bobby Fischer Against the World," "Love, Marilyn" and "What Happened, Miss Simone?"

Ryan's credits include "The Office" and "Gone Baby Gone."
