Plot summary

The young thirty-something couple of Dan and Susan decide to go on holiday to the Caribbean. Of the many exciting activities available, the happy holidaymakers choose scuba diving off a reef several miles out; however, due to a miscount, they will soon find themselves left behind in the cold, vast sea. Now, as they drift endlessly for hours, the extreme dehydration, the severe saltwater sickness, and the nasty jellyfish stings will be the least of Dan and Susan's worries, as fleeting sightings of what can only be a shark, can only mean one thing: if the search crew doesn't find them first, the couple will become the unstoppable predator's next meal. Can they survive the wild open ocean?—Nick Riganas
