Scott Wilson, FBI, shows up in Suddenly, Montana, piloting a stealth-like helicopter named Delilah. Using a fictitious name, he rents an apartment from a female forest ranger, Julie Drum, who he is immediately attracted to, and her to him. She is a widow with two sons and afraid to become involved with a man having an unknown future.

The little town of 1,800 souls in the Bitterroot Mountains is policed by a severely overweight sheriff and one deputy who are not prepared to confront kidnappers, and request assistance. A second agent, a female, joins Scott to help protect Megan Isaacs, a pretty sixteen-year-old.

When the protection scheme blows up, how are the authorities going to find Megan and avoid making a half-million dollar ransom payment? Will Scott and Julie have a future together?
