Danzer, a self-described "nobody," has pulled off a stunning theft of diamonds. He is on the run from Becker, hired by the owners of the stones. Danzer steals a plane but is forced to crash land after a gunshot from Becker has pierced the fuel tank of the airplane Danzer has stolen. Danzer, desperate, kidnaps a blind woman as he attempts to flee the United States. Erskine and Daniels lead the FBI's investigation, seeking to apprehend Danzer before he can get into Mexico. The FBI men are racing Becker to get there first. Becker has his own ideas what to do with the diamonds.
