When a B-29 bomber strays from its course, its crew — high-living pilot Noah Dugan (Elliott Gould), a prim missionary (Geneviève Bujold), her cargo of farm animals, and two stowaway orphans -- must make an emergency landing on an unmapped island in the South Pacific. In order to survive, the foursome, along with two unexpected allies, convert the downed plane into the oddest sea-going vessel ever and then set sail -- animals and all -- on a perilous search for civilization in this Disney adventure for the whole family.
