A B-29 bomber has an unusual roster of guests onboard: A man running away from bookies, a missionary, two children who have stowed away, and some farm animals. On the way to the South Pacific, the plane is forced to make an emergency landing, and they all find themselves stranded on a remote tropical island, which they assume to be deserted until they run into two Japanese soldiers who have lived there since World War II. The group work to turn their plane into a boat so that they can take the animals and escape.
