Sneak Peek: Pretty Little Liars Midseason Finale

All is not what it seems for four Pretty Little Liars as "A" sends them on a hunt to destroy lives in order to save another.  "Over My Dead Body," the midseason finale of ABC Family's hit original series Pretty Little Liars is airing tonight, and you don't want to miss out!

Aria, Emily, Hanna, and Spencer have made a crucial mistake -- they told someone about "A" and now they must pay the price.  With the clock ticking and "A" calling the shots, the girls are sent on missions to do "A's" bidding in order to save their trusted confidant.  Each misison will ultimately lead to what the four liars want the most, but as a costly price to their loved ones and themselves.  Can Aria, Emily, Hanna and Spencer go through with their given tasks in order to save one, or will they ignore "A" to save those around them from being hurt?  And ultimately, will this matter when all is said and done?  Nothing is ever as it seems in Rosewood, PA.

Tune in tonight (August 30) to ABC Family at (8:00 - 9:00 PM ET/PT).
