Venerable British actress Susannah York and up-and-coming star Radha Mitchell head up the cast of this Australian psychological thriller. Both actresses play the character of Carolyn at different stages of her life; bookended with scenes of the elder Carolyn (York) recalling her attempt to sail around the world, the bulk of the film involves the terror-stricken voyage itself. Only in her twenties, the young Carolyn (Mitchell) is filled with hope and fear for her daring solo journey, but once at sea, isolation and solitude begin to take their toll. Soon, Carolyn is encountering people and situations from her past, sometimes with violent, terrifying consequences. When she begins to notice physical evidence of her nightmarish visitors, Carolyn really begins to lose it. ~ Michael Hastings, All Movie Guide
