On Adventure Island

Two twin sisters undertake a daring flight to South America, one reveling in aerobatics while the other keeps a steadier course. Their journey brings aerial chases, a violent tropical storm that separates companions, and a scheming foe who captures their plane and leaves them stranded on a desert island. Faced with wrecked aircraft, island camps, hidden caves and growing danger, the girls draw on courage, quick thinking and their bond to attempt escapes, confront their captors and survive a series of episodic adventures that blend action, suspense and resourcefulness.
