 Society glamour girl/aviatrix Virginia Allerton (June Lang) decides to alter her around-the-world flight by stopping off on the Pacific isle of Palo Pango where her brother, Lieutenant Allerton (Grant Richards) is stationed with a detachment of U.S. Marines, including "Stripes" Thornton (William Gargan) and "Milly" Barnes (Wallace Ford.) Local smuggler Barton (Gilbert Roland) baits her into a trap using her plane for his gun-smuggling racket and she ends up wrecked on another island. Thornton, as a stowaway on Barton s gun-smuggling plane, and Barnes, by water in a stolen speed boat, rush to her rescue. Inda (Katherine DeMille), the jealous native wife of Barton, with a penchant for dispatching people with poison darts from a blow gun, does her best to do the same for Virginia.
