Pretty Little Liars

"Got a secret, can you keep it?  Swear this one you'll save.  Better lock it in your pocket, taking this one to the grave." 

Pretty Little Liars is mystery kind of show based off of the 15 (the book series isn't over yet) part series by Sarah Sheppard.  In the show, four friends Emily Fields, Hanna Marin, Aria Montgomery, and Spencer Hastings find themselves being stalked and tormented by an unknown person who goes under the name A.

The girls often receive texts or a note threatening to reveal some of their biggest secrets if they don’t do as A asks.  The girls suspect it to be their friend Alison DiLaurentis, who is the only person they had ever shared these secrets with.  Though they often dismissed that hunch, Alison has been dead for a year after all.  It doesn't help that A often shows up wearing a mask modeled after Alison's face.  

In the most recent season the girls have found that there is more than one A, and that they are all just being controlled by a single ring leader. These new As' are known as 'red coat' the reason is simple, they wear red coats. In this season the girls have spent more time than ever trying to take down, and reveal who the main A is.  They have found Alison’s old diary and they discovered that A must have been using the book to blackmail the girls because the content of the pages is all the girls deepest secrets. 

          One thing is for sure, if you think you know what is going to happen, or who A is, it’ll probably turn out in a whole unexpected way.
