A great white shark hunts the crew of a capsized sailboat along the Great Barrier Reef.
The Reef is a 2010 Australian horror film. The film was written and directed by Andrew Traucki, his second feature film (the first being Black Water), and is about a group of friends who capsize while sailing to Indonesia. The group decides that their best bet for survival is to swim to a nearby island but they find themselves stalked by a great white shark.
