Based on the series of young adult novels by Sara Shepard, Pretty Little Liars follows the lives of four teens—Hanna (Ashley Benson), Spencer (Troian Bellisario), Aria (Lucy Hale), and Emily (Shay Mitchell)—whose friendship and personal lives become strained after the supposed death of the head bitch, Alison (Sasha Pieterse). At the one year anniversary of Alison’s demise/disappearance, they group of gals begin receiving messages in various forms from someone using the name “A”. The mysterious messanger threatens to expose the girls’ secrets, include ones that only Alison knew. Weird stuff! As the teens continue to find themselves in precarious and dangerous situations, they must band together to find out who A is and stop her/him/them. Since the little liars are little hotties, they wrangle up some pretty hot love interests. There’s Ezra (Ian Harding), the group’s artistic and sensitive English teacher; Toby (Keegan Allen), the James Dean-ish bad buy that’s not afraid to lose his shirt and show off his underwear model physique; and Caleb (Tyler Blackburn), the slacker computer hacker with an equally hot body. Throw in a secondary cast full of hotties like Brant Daugherty, Drew Van Acker, Yani Gellman and Chuck Hittinger, and this tweener series will put a sexual spark in your loins!
