When a railroad engineer is shot dead, and it is determined that the bullet came from a sniper's rifle more than six hundred yards away, all eyes turn on Deputy Sheriff P. A. Pennington as a suspect. Pennington-the man who solved the Wheat Field murders-is by far the best marksman in town, and had been an Army Ranger sniper in the war. When the engineer's young and sexy wife is shot dead days later, he realizes that his worst nightmare is about to begin.
During the war, Nazi SS Colonel Christian Wolfgang Stangl-known as "the Wolf"-controlled the narrow mountain railroad pass in the Bavarian Alps used to ship millions of dollars in gold and war loot. Pennington had been sent on a suicide mission to shut down the pass-but the Wolf got away. Now it appears as if the Wolf is at his door.
