The Reef (2010)

Beneath the turquoise splendor of the Great Barrier Reef, a primal terror lurks. The crew of an overturned sailboat find themselves adrift, their idyllic voyage shattered, and hope dwindling with the setting sun. A formidable great white shark, an apex predator of unimaginable size and ferocity, has marked them as prey. Stranded and vulnerable, they must summon every ounce of courage and ingenuity to survive its relentless attacks. This is a battle for survival against an ancient force of nature, where the hunter's instinct clashes with the human will to live, leaving audiences breathless until the very end.
