This movie is based on the true story of 23-year-old Tami Oldham (Woodley) and her fiancé Richard Sharp (Claflin) who set out on a romantic sailing trip from Tahiti to San Diego. A few weeks into the trip, however, the couple unexpectedly encounter a hurricane – which just so happened to be one of the most catastrophic in recorded history.

In the aftermath of the storm, Tami finds their boat ruined and Richard badly injured. There is no radio and the nearest help is in Hawaii, 1500 miles away. With no hope for a miraculous rescue – and only her wits to rely on – Tami must find the strength and determination to save both herself and the love of her life.

If you’ve read the book by Steven Callahan, on which this is based, expect something quite different. Baltasar Kormákur, the Icelandic director of movies such as The Deep and Everest, deftly balances the love story elements with a gripping survival drama – with the ocean as another character as much as anyone in the cast. But be warned: if you suffer from motion sickness, the recreated footage of the hurricane may test your limits.
