“A” and a new group of Liars stirring up trouble in the trailer for HBO Max’s Pretty Little Liars: Original Sin

The series stars Bailee Madison, Chandler Kinney, Zaria, Malia Pyles, and Maia Reficco as the new generation of Liars. It also stars Mallory Bechtel, Sharon Leal, Elena Goode, Lea Salonga, Eric Johnson, and Alex Aiono.

The series is executive produced and written by Roberto Aguirre-Sacasa and Lindsay Calhoon Bring.

Here's the official description:

Twenty years ago, a series of tragic events almost ripped the blue-collar town of Millwood apart. Now, in present day, a disparate group of teen girls — a brand-new set of Little Liars — find themselves tormented by an unknown Assailant and made to pay for the secret sin committed by their parents two decades ago…as well as their own. In the dark, coming-of-age, 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.

The new series debuts later this month.

Pretty Little Liars: Original Sin is set to premiere on HBO Max Thursday, July 28. The 10-episode season will debut with three new episodes. Two new episodes will follow on August 4 and 11 and the final three episodes will debute on August 18.
