Mystery in Mexico

On a flight to Mexico City, insurance investigator Steve Hastings (William Lundigan) befriends singer Victoria Ames (Jacqueline White), attempting to get information about her missing brother, fellow investigator Glenn Ames (Walter Reed), who the firm suspects may have taken a stolen necklace he was tasked with recovering. Their search for Glenn leads them to nightclub owner John Norcross (Ricardo Cortez) and his sometimes girlfriend, singer Dolores Fernandez (Jacqueline Dalya). Taxi driver Carlos (Tony Barrett), who has been helping Hastings, turns out to be Norcross's stooge, and reveals to the nightclub owner where the injured Glenn has been recuperating with a simple Mexican family.
