After Trailer: Oh! Darling … If You Leave Me, I’ll Never Make It Alone
After deals with two survivors of a bus crash, (Steven Strait & Karolina Wydra) who were both separately heading back to their small hometown of Pearl after long absences. When they do finally find themselves there, they realize the town's population has completely vanished with no sign as to why. They begin to explore Pearl together trying to determine what's happened. They discover an ominous wall of darkness both surrounding the town and slowly overtaking it.
There seemed to be several elements taken from other horror stories, Steven King's The Langoliers and Vanishing on 7th Street both come to mind. The movie's title also suggests it might have given away a Shyamalanian twist.
After comes to theaters September 12th.
