Plot

In the border town of Hernandez, New Mexico, undercover agent Mark Owens (Charles Quigley) is assigned to help the United States Border Patrol break up a well-organized band of smugglers. Hernandez also has a reputation for "quick marriages", just across the border in Mexico, so Mark soon signs on as a pilot on "The Honeymoon Express."
