It's Judgement Day for Alison on Tonight's 'Pretty Little Liars' - See the Pics!

Caleb (Tyler Blackburn) and Ezra (Ian Harding) team up in this still from tonight’s all-new episode of Pretty Little Liars.

In “I’m a Good Girl, I Am,” Alison’s (Sasha Pieterse) trial is coming to a close, and the outcome looks even more bleak when the prosecution calls a surprise witness that not only paints Alison in a bad light but also the PLLs and Mike (Cody Christian).

Desperate to find any evidence or witness to save their friends, Aria (Lucy Hale), Emily (Shay Mitchell), and Spencer (Troian Bellisario) race to find someone or something that can prove Ali’s innocence and put an end to this nightmare.

Pretty Little Liars airs TONIGHT, March 17 @ 8PM on ABC Family.
