SOS Pacific(1959)

Overview:

A flying boat has to ditch off an island in the Pacific. Along with the injured owner-pilot the passengers include a policeman and his smuggler prisoner, a slimey limey witness against him, a physicist, and a globe-hopping good-time girl. On the island they find a fleet of derelict ships, farm animals tethered, and cameras in a lead-lined bunker and a stark realisation soon dawns.
