Rancher Roy Carlson asks Frank and Joe to visit his spread in New Mexico after one of his cowboys disappears. While searching the area in an ultralight plane, the Hardys are forced to land.
Suddenly the brother detectives are fighting to survive in a vast wilderness -- and along with rattlesnakes and tornadoes a deadly enemy is on their trail. There's a million-dollar bonanza at stake as Frank and Joe uncover the real mystery of the Circle C Ranch. But unless the brothers make their way home, their lives won't be worth a plugged nickel.
