Season two begins moments after the explosive season one finale and the girls are the talk of the town. Surprises and challenges will be in store for each, and "A" may succeed in her quest. Emily, Hanna, Spencer, and Aria are crumbling under the constant pressure of A's relentless texts and the knowledge that A inexplicably knows every little detail of their lives, including their thoughts, and is watching and anticipating the girls' every move. Spencer's family is falling apart. Aria and Ezra's relationship gets even more complicated, and Aria's brother Mike finds himself in trouble with the law, while their parents find themselves tested like never before.
