A pilot, who is an atheist, is flying over the ocean in a small plane with a friend, who is a Christian.
They run into bad weather and crash on an uncharted, deserted island with no hope of ever being rescued.
They both survive the crash, but suffer permanent amnesia due to a head injuries. The only useful thing that they remember is how to read.
Surviving the crash with them are two books: one is a book on island survival tips, including farming, edible plants, hunting and fishing, and the other book is the Bible.
