In the small American town of Millwood, a group of teenage girls are made to pay for their parents’ sins when they become the unwilling recipients of an anonymous blackmailer, following a series of tragic events that occurred twenty years earlier.
Twenty years ago, a series of tragic events almost ripped the blue-collar town of Millwood apart. Now, in the present day, a group of disparate teen girls — a brand-new set of Little Liars — finds themselves tormented by an unknown Assailant and made to pay for the secret sin their parents committed two decades ago, as well as their own. In the dark, coming-of-rage, horror-tinged drama Pretty Little Liars: Original Sin, we find ourselves miles away from Rosewood, but within the existing Pretty Little Liars universe — in a brand-new town, with a new generation of Little Liars.
Maia Reficco as Noa Oliver: A striving, sardonic track star who’s working hard to get her life back to normal after a summer spent in juvenile detention.

Zaria as Faran: A poised, disciplined ballerina with aspirations to make it out of Millwood. But ‘A’ isn’t the only villain in Faran’s life. In the world of ballet, it is death by a thousand micro-aggressions.
Malia Pyles as Minnie: The youngest of the Little Liars. Having survived a childhood trauma, Minnie spends most of her time in a virtual world, but she is more than capable of taking on the dark forces of Millwood — including ‘A'.

Derek Klena as Wes: Tabby’s boss at The Orpheum, Millwood’s second-run local movie theater. A devilishly handsome film school graduate, Wes and Tabby have bonded over their mutual love of film, but Wes’s intentions are anything but pure.

Lilla Crawford as Sandy: Karen’s most ardent admirer. A cringey tagalong, Sandy often boosts Karen’s ego in an effort to stay out of her best friend’s crosshairs.
Brian Altemus as Tyler: a Millwood High jock. No stranger to “locker room talk,” Tyler is the poster child for young, toxic masculinity.
Cristala Carter as Nurse Simmons: the School Nurse at Millwood High. Nurse Simmons is a confidante and safe place to land for our Little Liars.
Anthony Ordonez as Mr. Gardner: the Computer Science Teacher at Millwood High. Known as Mr. Gee, Mr. Gardner is a mentor and friend to Minnie.
