About Pretty Little Liars: Original Sin

Twenty years ago, a series of tragic events almost ripped the blue-collar town of Millwood apart.

Pretty Little Liars: Original Sin runs for 2 seasons, created by Roberto Aguirre-Sacasa and Lindsay Calhoon Bring. Every episode page keeps the show's order, so you can watch from the pilot to the finale without hunting for the next link. Episodes are bought individually for 1 credit.
