Aria drops her brother Mike off at lacrosse practice before heading to a local bar, where she spots a missing persons poster of Alison. She then spots a cute Hollis College grad named Ezra sitting a few stools down. The two talk about their travels in Europe, specifically Iceland, music, and their love of English literature. Ezra says he is teaching English, though does not specify where. In addition, Aria is vague about where she attends school. Their meeting ends with the two making out in the bar bathroom. When their best friend mysteriously vanishes, four girls believe their secrets are safe forever. But when they begin to receive threatening messages, the truth may be only one text away. Set one year after the disappearance of Alison DiLaurentis, the manipulative and vindictive queen bee of their group, the series revolves around four 16-year-old girlfriends — Aria Montgomery, Spencer Hastings, Hanna Marin, and Emily Fields — who have lost touch with one another until each begins to receive mysterious messages from "A," suggesting that Alison is watching them. Linked by their former bond and the panic and confusion the enigmatic messages cause, the friends are suddenly reunited, though each girl has her own secrets — secrets she wants no one else to know. #PLL #PrettyLittleLiars
