See All The Sneak Peek Clips From 'The Perfectionists' Premiere!

Mona (Janel Parrish) looks so ready for pie with Alison (Sasha Pieterse) in this still from the premiere episode of The Perfectionists.

In the first ever episode, everything about the town of Beacon Heights seems perfect, from its top-tier college to its overachieving residents-but nothing in Beacon Heights is as it appears to be.

When the high-stakes environment pushes the residents to a breaking point, someone snaps and kills someone. As they work together to solve the murder mystery, it soon becomes clear that behind every Perfectionist is a secret, a lie-and a needed alibi.

Pretty Little Liars: The Perfectionists premieres TONIGHT, March 20th @ 8PM ET/PT on Freeform.
