Pretty Little Liars: The Perfectionists - What2Watch

On the night that a school gala is scheduled to take place, the gang meets and agrees that they're pretty sure about who was responsible for Nolan's murder, so they decide to set out to prove it in a new episode called "Lie Together, Die Together." The sense of shared purpose is compromised, however, by Dana (Klea Scott), who exposes a critical secret held among the group. Sofia Carson, Sasha Pieterse, Kelly Rutherford and Janel Parrish also star.
