My interpretation of this movie is that they are living in a post apocalyptic world after the rapture and it's dangerous so this small area has a kind of law to keep the peace. This guy finds out there's a way to get to paradise even though the rapture has already happened and these remaining people were not raptured. He follows the clues into the lawless desert and in the end finds a skull which after meditating on it's meaning he realizes that the skull is death so that is the way. He asks the other guy to bury him so that he can die and enter paradise the only way possible. He is buried, dies, and his soul awakens at the door in which he enters Paradise. The girl on the bench in Paradise tells him to imagine whatever he wants but he realizes he wants to go through another door to return to where he came from because he left his brother behind.
