Angels are among us and when we feel an invisible presence, you better believe they are watching you. For a Los Angeles heart surgeon named Maggie, that is too much of a stretch. She believes that it is her job to save the lifes of her patients and when she meets Seth after visiting hours are over, he tells her it's simply just their time to go. She becomes intrigued by his presence and opinion. Seth is not just normal, he is an Angel. He meets Messinger while visiting patients. Messinger can see him because he was once a Angel but gave his power up to become human. This makes Seth want to become human so he can feel, smell, and love Maggie.
