When Black Birds Fly (2015)

Heaven is a beautiful, clean suburban paradise. Every block is populated by lush trees and lovely row homes. People are free to roam and do whatever they please, as long as they follow one simple rule: DO NOT communicate with "The Evil One" that dwells on the other side of a giant wall that circles the town, which is under 24 hour surveillance by a team of soldiers wearing gas masks.

The ruler of the town is a man named Caine, who plasters images of himself all around town, insisting that his citizens trust and love him. A small child becomes obsessed with the seemingly increasing flocks of black birds that populate the town. One day after chasing one he discovers a talking kitten with a broken leg, who begs Marius and his classmate Eden to crawl through a hole in the wall to help her. The kids decide to do it and she repays them by introducing them to a brightly colored fruit that grows wildly on the other side of the wall. After consuming it the kitten brings them to meet the Evil One, who attempts to teach them the forbidden knowledge that Caine is hiding from them all.
