In a Heaven run like a business by a female God, poor returns from the angels are making God disappointed. She decides to set an example, by destroying Las Vegas with floods and fire when she sees that Las Vegas is living up to it's name of Sin City. An unhappy angel Miles, trying to find a purpose to his existence, pleads on their behalf. He makes a deal with God, that if he can locate six virtuous people before the deadline, Vegas will be spared. He takes on human form, and meets Verna, the girlfriend of a mobster, and he finds himself attracted to her. But it's not long before he realises it's harder than he expected to find anyone with true virtue.
