"Today is the day I'm going to die." "No, today's the day you're going to survive." Angela Moriarty was a fallen angel and not just any fallen angel she was a product of God and Satan; an immortal. Dean Lucifer is a boy destined to fail in life; he's human and if he thought life was weird just wait until he sees Angela falling from the sky. This duo will fight monsters and try not to fall in love but you never know maybe fallen angels never survive love.
