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 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.
Unfortunately the series Pretty Little Liars: Original Sin is not yet available on Paramount Plus.
