Alan Lloyd (Hill) is an inveterate gambler who accumulates a lot of debt and therefore is forced to flee, pursued by shady employers in the area.

Charlie O'Brien (Spencer) is an actor who is hired to advertise a jam (that tastes horrible) and is embarking on a long promotional boat trip.

The man receives Alan and Charlie in his bunker and shows them a huge amount of money (stolen from the United States Navy during the war) that he kept hidden for years.

Charlie plans to leave with an old plane but the pirates inadvertently come back to the island more aggressive and with the incursion of a group of criminals who had the honor to clash with Alan at the beginning of the story.

The natives are captured and humiliated, so Alan and Charlie, who had gone off (without the latter having discovered the secret of fake money), come back, swoop down with the plane on the attackers and fight their enemies in a battle to the sound of blows and punches, finally defeating them and bringing lasting peace to the island.
