In 1960, a hardy group of prep school students boards an old-fashioned sailing ship. With Capt. Christopher Sheldon at the helm, the oceangoing voyage is intended to teach the boys fortitude and discipline. But the youthful crew are about to get some unexpected instruction in survival when they get caught in the clutches of a white squall storm.

In the South Pacific island of Makatea, career-driven magazine editor Robin Monroe is on a week-long vacation getaway with her boyfriend, Frank Martin. An emergency work assignment in neighboring Tahiti requires Robin to hire the cantankerous pilot Quinn Harris who had flown them to Makatea on a small transport plane. While flying, a powerful storm forces Quinn to make an emergency landing on a nearby deserted island. The dissimilar pair avoid each other at first, until they're forced to team up to escape from the island -- and some pirates who want their heads.
