U.S. Army Air Corps buddies Lt. Jerry Doyle (
Kenneth Harlan) and Lt. Andy Conroy (
Charles Delaney) enlist in the U.S. Air Patrol. They are assigned to the mission of fighting alien-smuggling along the USA-Mexico border. When the pair are sent across the Mexican border disguised as smugglers to break up a gang, they both fall in love with Dolores (
Josephine Dunn), the dancer in a Mexican cantina where the smugglers led by Pascal (
Richard Cramer), hang out. When Andy visits Dolores at the cantina, he is captured by the smugglers. One of the gang discover the aircraft that Jerry and Andy have hidden away and see the air patrol logo on its side. Andy escapes and takes off in his aircraft, followed by the smugglers. In the air battle that follows, Andy is shot down, but before he dies, he relays a message to Jerry. Refusing help from his fellow air police, Jerry determines to avenge Andy's death. Suspecting that Dolores was helping Pascal, he flies across the border to confronts her at the cantina. While at the cantina, Jerry is captured by Pascal who ties up Jerry and places him in the cockpit of his own aircraft, but Dolores comes to help him escape. Pascal follows in his aircraft using Dolores as a hostage. During the ensuing battle, Dolores parachutes to safety and Pascal is killed. After Jerry lands, Dolores explains that she had nothing to do with Andy's death, and she and Jerry are reconciled. ==Cast==
