Based on the best-selling book series, Pretty Little Liars returns for another suspenseful season. In season one, as four 16-year-old girlfriends -- Aria, Hanna, Spencer and Emily -- dealt with the aftermath of their best friend Alison's mysterious death, they believed their secrets were safe forever. Yet they began to receive threatening messages from someone named "A" who seemed to know their most private details - threatening everything they held dear in their picturesque suburban community. The drama continues as season two begins moments after the explosive season one finale. The girls are the talk of the town -- and not in a good way. Whoever said that change is good has never visited Rosewood, PA... or come across four pretty little liars.
