In an apocalyptic landscape, God has lost faith in humanity and sends his legion of angels to bring about the end of the world. Archangel Michael defies God's will, cuts off his wings, and descends to Earth to protect a group of strangers who find themselves unwittingly thrust into a celestial battle. Among these strangers is a pregnant waitress named Charlie, who works at a remote diner in the Mojave Desert, owned by Bob Hanson. The diner's inhabitants become the focal point of Michael's mission, as he believes that Charlie's unborn child holds the key to humanity's redemption and future.

As the world plunges into chaos with signs of the apocalypse emerging, the diner becomes a fortress under siege. The patrons are terrorized by possessed humans sent by the angel Gabriel to kill Charlie and her baby. Michael, armed with an arsenal of weaponry, prepares the diner's residents for the impending siege. As they fight for survival, they come to realize the significance of the child Charlie carries and the role each will play in determining the fate of humanity. Trust and faith are put to the test as they must stand together against the onslaught of heaven’s army bearing down upon them.
