Now, in the present day, a group of disparate teen girls—a brand-new set of Little Liars—find 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."
