HBO Max has given a direct-to-series order to a `Pretty Little Liars` reboot from `Riverdale` creator Roberto Aguirre-Sacasa, the streaming service said Thursday.

Titled `Pretty Little Liars: Original Sin,` the show will be set in a new town and follow a `new generation` of liars, but exist in the same universe as the Freeform series created by I. Marlene King and based on the novel series of the same name written by Sara Shepard. King is not involved in the reboot.

Here's the official description for `Pretty Little Liars: Original Sin`:

"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 - 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."
