"It's true what they say, you know: If you talk to God, you're religious; but if you hear from God, you're schizophrenic." When a car accident leaves a famous movie star in a coma, nurse Kemp McAvoy thinks he has found his ticket to the life he's always wanted. As a med school dropout who was on his way to becoming an anesthesiologist, Kemp has the knowledge to carry off the crazy plan he concocts: adjust the star's medication each night and pretend to be a heavenly visitor giving her messages. He recruits her agent and a down-and-out publisher to make sure the messages will become the next spiritual bestseller and make them all rich. But his girlfriend's daughter, Leah, keeps telling people that she is seeing angels, and her mother and her teachers are all afraid that something is wrong. Before it's all over, they'll all learn a few things about angels, love, and hope.
