Did the stork really deliver a baby boy to the roof of Sandra Coulton's isolated Alaskan ranch house? The ranch hands swear it's true, but Sandra, a wildlife biologist, is sure there's a rational explanation, even if she can't think of one. The baby distracts Sandra from her research on grizzlies, but not as much as Austin Smith, the ne'er-do-well, part-Cheyenne bush pilot who crash lands at the ranch and claims the baby is his. The pilot wants Sandra to be his, too, but she isn't looking for love, and she won't give up the baby. No one knows it, but the mysterious baby is actually the Archangel Geoffrey, who is suffering a bout of amnesia. If he doesn't remember his mission soon, he'll lose a bet with his rival Gabriel. Not to mention disappoint his boss.
