A series of mysterious plane crashes in the Rocky Mountains in the midst of a Depression winter call Air Corps reservists Mitch Sorley and Lewis Segura out to fly search and rescue, but it's more than just a simple navigational hazard.
Fortunately, Mitch and Lewis are more than just pilots. With Lewis' wife Alma and their old friend Dr. Jerry Ballard, they're members of an esoteric Lodge dedicated to the protection of the world.
The Silver Bullet Mine is haunted - or is it? Can ghosts bring down aircraft? And are the small-time crooks who are interested in the Mine simply looking to make a buck - or the vanguard of something more evil and deadly? Aided by their former con artist office manager Stasi Rostov, they've got to get to the bottom of what's happening at the Silver Bullet Mine before more lives are lost.
It may be that Jerry holds the key not only to Silver Bullet, but to an even more dangerous secret, one that men have killed to gain for 2000 years. The Lodge is in deep, and there is only one man who can help them, the legendary scientist Nikola Tesla!
