In the Pretty Little Liars Season 3 finale (Episode 24: “A dAngerous gAme”), the Liars are determined to unmAsk Red Coat. They’re done with her games — but has Spencer joined the “A” team? It certainly seems like it!
 
Whatever she's up to, she's finally home Radley and seemingly doing well, but Aria, Hanna, and Emily aren't so sure about her stability. “Spencer’s part of the ‘A’ team — game over!” says Aria. But how do they figure it out?

However, the Liars won't have much time to ponder Spencer's mental health (or lack thereof), because "shocking revelations are brought to the forefront. With so much happening and new information being uncovered, will the Liars be ready for what is waiting for them?"

Meanwhile, Spencer comes face-to-face with Red Coat, but is she ready for what she finds?

Catch the Season 3 finale of Pretty Little Liars on March 19 at 8 p.m. ET on ABC Family.
