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 do they try and swim for dry land? Taking to the water, the group start 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?
