 While preventing a robbery Erskine apprehends Oren McKay. He is wanted for his participation in an armored car holdup years earlier in which $2,000,000 was stolen. Seven men have now been arrested for their parts in the crime but the eighth man, Emory Hale, is still at large and only he knows the whereabouts of the money. McKay alludes to a shadowy ninth man who may have been an inside man on the job. The agents and the ninth man all begin circling around Anita Hale, Emory s wife in hopes of locating him. The trail takes them to the small border town of Las Rinas, New Mexico.
