In the 1950s, Arizona Deputy Sheriff Les Martin is pressured by his community to solve a string of mysterious murders around a mining ghost town in the Grand Canyon.

Helped by socialite Janice Kendon, Arizona Deputy Sheriff Les Martin works to solve three brutal murders in and around the Grand Canyon. His efforts lead to the killer fleeing with Janice as a hostage, and a chase by car and helicopter leading to a climax on a miner's bucket on cables a mile above the canyon floor.—Les Adams <[email protected]>
