Rick Ballinger is an aging war hero determined to sail alone to the South Pacific. Dr. Welby discovers that Ballinger has pernicious anemia, and warn the captain that such a voyage would prove fatal. Ballinger, however, goes ahead with his plan, since it is essential to him to maintain an heroic facade to impress his son and his young wife.
