A group of tourists find their lives changed forever after an exotic voyage to Asia leaves them shipwrecked and abandoned. As we discover later, it is no accident that thirteen people survive and find themselves stranded on an uninhabited island. Twelve of them were sent on this ill-fated cruise by business partners, parents or children, who, for one reason or another, did not want them to return.
Only one member of the group is there by pure chance. Who is the thirteenth man and why was this expedition organized? While mystery and danger lie in store, the survivors try to work out the answers to these questions and whether they can survive the treachery of their nearest and dearest.
