Two angels were cast out of heaven for trying to overthrow it. Now they want to take over earth with the men that worship them. Two more angels are sent to stop this tyranny. ...But who's going to stop God, the biggest dictator of them all?
You know that song "Angels Watching Over Me" by Amy Grant? Doesn't that make anyone paranoid. The things you do by yourself are embarrassing and to have some invisible, unverifiable winged spirits watching you and sniggering, that's just awful.
