One year ago, Alison mysteriously disappeared, and her four best friends were left to wonder what happened. Now, her dead body has turned up- but high schoolers Aria, Emily, Spencer, and Hanna have hardly found closure. They have started to receive texts from an anonymous "A" who somehow knows all of their secrets.
The girls had grown apart after Alison's disappearance, since it seemed that the manipulative popular girl was the only thing holding them together. As they search for the truth behind Alison's murder, "A" haunts them with their potentially life-ruining secrets, both old and new.
Pretty Little Liars seems silly at first, but is actually extremely addictive and surprisingly clever. The audience is kept guessing and enthralled by the show's many mysteries, and every character is well-developed and relatable. Each show usually ends on a scary and suspenseful note, with a twist thrown in to entice the viewer to come back for more. After watching an episode, it's almost impossible not to return for the next one.
Teenage girls will most enjoy Pretty Little Liars, as they can best relate to the four main characters. Aria, Emily, Spencer, and Hanna all have distinctive styles and are dressed extremely at all times. While this might seem a little unrealistic, it keeps the show interesting when the plot slows down.
Although the show is based off of a book series, the TV show's plot strays away from that of the novels, so that even the books' readers won't know all the answers.
