At school, Spencer and Emily spot a girl from the youth group with a jacket like the one Alison described that she saw while waiting at the playground. Emily and Spencer try to talk to the girl about her being in the playground on Thanksgiving Day but she freaks out. The girl sees Ella in the hallway and accuses her of telling Aria and her friends a secret she promised to keep and storms off. Emily and Spencer are baffled.
Alison’s 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. Desperate to find any evidence or witness to save their friends, Aria, Emily and Spencer race to find someone or something that can prove Ali’s innocence and put an end to this nightmare. Meanwhile, Mike becomes a target of “A” when it looks like he might be called to testify and Ezra and Caleb have differing opinions on what he should do. #PLL #PrettyLittleLiars
