It's moving day for Emily, and with a new place to call home, she is feeling more like a guest than part of the family. Hanna is also feeling uneasy, but for her it is in regards to Caleb's continued shady "business" dealings and his nonchalant attitude about it. And when Toby makes a surprising discovery, Spencer is thrown for a loop by the find and her father's reaction to it. With the girls already on edge, could they be sitting targets for "A's" next move? Or does "A" have bigger plans for the four and is just making them wait? Meanwhile, Aria is put in a tricky position when both Ezra and Jason are invited to the Montgomery dinner party and vie for her attention when the soiree goes awry.
