The girls scramble for evidence as Alison contemplates a plea deal that would incriminate one of the PLLs in "To Plea Or Not To Plea," an all-new episode of ABC Family's hit original series "Pretty Little Liars," premiering Tuesday, March 3rd (8:00 - 9:00 PM ET/PT).
Aria, Emily and Hanna keep looking for a way to prove Ali's innocence without incriminating Mike. But when the D.A. proposes a plea bargain agreement for Ali that includes naming one of the PLL's as her accomplice, the girls intensify their search - not only to save Ali but to save themselves. Will Ali stick by her story of innocence, or will she give up one of the PLLs to save her own skin?
Meanwhile, not knowing what is happening back in Rosewood, Spencer gets a much needed break from all the drama with a night out on the town in London.
