Pretty Little Liars

Pilot (1x1)

:

Aria returns to Hollis a year after the mysterious disappearance of Allison and picks up her friendships with Spencer, Hanna & Emily. The girls are stunned when Allison's body is recovered, turning the missing persons case into a murder. Even more disturbing is the message they all receive that spooks them into wondering if their presumably-deceased friend could still be alive.
