"One Day She'll Darken tells the incredible story of Fauna Hodel who was given away by her teenage birth mother to a black restroom attendant in a Nevada casino in 1949," a synopsis explained. "As Fauna begins to investigate the secrets to her past, she follows a sinister trail that swirls ever closer to an infamous Hollywood gynecologist, Dr. George Hodel, a man involved in the darkest Hollywood debauchery, the spider in the web around the legendary 'Black Dahlia' murder of Elizabeth Short in Los Angeles in 1947."
Sam Sheridan wrote the six-episode program, with shooting scheduled to begin this fall.
"Patty Jenkins is a phenomenally talented director who has always delivered powerful characters, from the unforgettable true-life serial killer in Monster to the game-changing superhero warrior in Wonder Woman," Sarah Aubrey, executive vice president of original programming for TNT, said in a statement Thursday. "One Day She'll Darken is a mind-boggling true mystery with unpredictable twists and turns and edge-of-your-seat chills. Sam Sheridan, an expert storyteller, has delivered scripts that entertain, frighten and tell tales of redemption and a powerful search for identity. Chris Pine has wowed us with so many of his performances, and knowing how multi-dimensional his character is in One Day She'll Darken, we are so lucky to have an actor as talented as he is to lead this cast."
