Surrounded by hostile Comanches, frontier widow Celia Gray knows the only hope she and her little boy have is to escape to Fort Dobbs. Their escort is Gar Davis, a strapping stranger who clearly has something to hide. Celia fears she knows his secret: he's the man who murdered her husband. Clint Walker plays the mysterious stranger and Virginia Mayo is the ravishing widow in this Western tale of high-desert suspense and action. As the desperate travelers make their way through Indian attacks and the perils of a forbidding terrain, they're joined by a gun trader (Brian Keith in a audience-grabbing performance) carrying high-performance rifles he's looking to sell ' and Gar worries that the Comanches will be the highest bidder.
