Four backpackers set out for a week cruising the beautiful great barrier reef on their own yacht. When the boat capsizes leaving them stranded on the overturned hull they must make a simple choice...stay with a damaged ship, likely to sink at any moment or swim for dry. Taking to the water the group starts to close in on land but when a giant fin breaks the surface they are hit with the realisation they are being stalked by a deadly fourteen foot Great White shark. Will any of them make it to dry land or will the sea just take what it wants?
