ABC Family has a new show this summer called 'Pretty Little Liars.' It's about four friends who reunite in their hometown a year after their other friend Allison goes missing. They start getting all-knowing text messages from someone with the name "A."
This is just a quick teaser trailer, but it looks like a mix of 'Gossip Girl,' 'Harper's Island,' and all those shows and movies where really attractive people wear great clothes and have unprotected sex while something mysterious happens. It's based on a series of novels, including Pretty Girls: Flawless and Pretty Girls: Wicked and stars Lucy Hale, Laura Leighton, Troian Bellisario, Nia Peeples, and Ashley Benson.
