The federal agent "at large" in this Republic programmer is played by Kent Taylor. On the trail of gold smugglers in Mexico, Matt Reedy (Taylor) crosses the path of hard-boiled lady criminal Solitare (Dorothy Patrick). Her criminal tendencies softened by romance, Solitare decides to work with Reedy instead of against him. The gang's modus operandi is an ingenious one; equally clever are the means by which they are brought to justice. Second-billed Robert Rockwell delivers one of his better performances as a dedicated archaeologist, while veteran character actor Frank Puglia enjoys one of his largest screen roles as a reluctant outlaw.
