Pretty Little Liars: Original Sin

In Season 2, our PLLs face down summer school and a new villain — who may or may not have a connection to "A" — ready to put them all to the test.

In 1999, tragic events threatened to rip apart a close-knit circle of friends and the small town of Millwood. Twenty years later, a new group of Millwood High students is hunted by an assailant known as "A," who threatens to make them pay for their parents' past transgressions and sins of their own.
