The glamorous heiress and daredevil pilot Virginia Allerton is test-flying her seaplane "The Lady Bird" after some modifications made by her mechanic Max Raft, also on the aircraft. They experience problems mid-air when they are caught in a tropical storm, and all the ships in the South Sea area are alerted to their distress. Virginia's brother, Lt. George Allerton, is stationed with the U.S. Marine Corps on the nearby island of Palo Pango when he hears his sister's distress calls. Virginia and Max head to the island to take refuge from the storm. Upon their arrival, Virginia and Max are welcomed by two U.S. Marines: "Stripes" Thornton and "Milly" Barnes. Also present is Oliver Barton, who runs the trading post but is also in the business of smuggling guns. He invites Virginia to stay at his house for the night, and also challenges her to a flying race to Guam, betting $5,000 that he will win. Both Marines are soon smitten by Virginia, and she becomes attracted to Stripes. Virginia is unaware that Barton is planning to use her as cover for his shipment of guns about to take place on the steamer Albotros, commanded by Captain N. Lawson. To help him, Barton has an assistant, "Doc" Spriggs, an old eccentric gentleman who believes in reincarnation. The race begins and Barton tries to outrun Virginia by taking a perilous shortcut over an island. Barton plays a trick on Virginia by faking his aircraft crashing into the jungle. Virginia lands on the water to rescue him but damages her aircraft in the process. It turns out Barton lives nearby and Virginia and Max are invited to be the guests of him and his Caribbean wife Inda. Inda believes that Barton is smitten and becomes jealous of Virginia. Max finds evidence in Barton's aircraft of his gun smuggling operation, and a fight between the men ensues. Inda kills Max with a poisoned dart she fires from a blowgun. Barton flees the island and goes back to Palo Pango. He lies to Stripes, telling him he has no idea where Virginia is, but Stripes finds a poisoned dart stuck into the hull of the aircraft and becomes suspicious. He deploys Milly and they follow Barton. Stripes hides aboard Barton's aircraft and manages to tell the others where they land. He finds Virginia in Barton's jungle home, but Inda alerts Barton and Stripes and Virginia are quickly surrounded. Still, Stripes manages to hold Barton captive. The group escape boarding Barton's aircraft but it will not start. Barton runs off in the midst of a shoot-out, Milly arrives, armed with his hand grenades, and joins in to help Stripes. Barton captures Virginia and brings her with him in his escape, but Inda spots the two of them, and furious with jealousy, gives the order to have him shot. A ship of Marines arrive on the scene and save the day, helping them back to Palo Pango. Virginia and Stripes marry and fly off to Honolulu together on a honeymoon, leaving Milly, now promoted to sergeant, behind.

Production
The working title for the film was Trouble over the Pacific with principal photography beginning in 1939 on Santa Catalina Island, California. Produced by Franklyn Warner originally for Grand National Pictures, however, by the time of the film's production, in late 1939, Grand National had gone bankrupt, subsequently, RKO bought the distribution rights to the film. Karen Morley was originally cast in the role of Virgina, but due to illness, was forced to leave the film and was replaced by June Lang. There was a two-week shooting period on location in Catalina, California from May 24 to late-September 1939. At the time of its production, Isle of Destiny had the biggest budget of any Fine Arts picture to date and marked the introduction of Cosmocolor to feature films. Aviation film historian Christian Santoir compared the scenario depicted in Isle of Destiny to that of the real-life tragedy of Amelia Earhartbeing lost in the South Pacific. He also described the aviation elements as relying on a Sikorsky S-39-CS Special c/n 914, NC-52V and a Stearman C3R aircraft for the "air race".
Reception
B.R. Crisler in his review of Isle of Destiny for The New York Times, noted, "The authors of the Rialto's current excursion in melodrama, "Isle of Destiny," certainly deserve to be commended for their resourcefulness, if for nothing else, because they have succeeded in cramming into one feature-length picture practically all of the tricks known to the adventure story. In fact, the writers seem to have been so impressed by the plethora of material that they didn't pay much attention to continuity. As a result the film becomes somewhat entangled at times in its own plot manipulations." Film historians Richard Jewell and Vernon Harbin in The RKO Story considered Isle of Destiny, "laughable exoticism" with "... wretched screenplay... frenzied direction and inept performances by the lead actors..."
