An idyllic holiday cruising the backwaters of the South Pacific becomes a voyage into hell for a group of passengers on board The Sea Tramp. The magnificent sailing boat is set upon by modern day pirates and seized in a bloody battle which claims the lives of many. Those who escape the pirates find themselves marooned on a deserted tropical island. Putting aside their not inconsiderable differences, they band together to ensure their own survival. With the constant threat that the murderous pirates will return to finish the job, the members of this tribe depend on each other for their very existence. But they will soon discover they not only have to protect themselves from external threats, but from the treachery of one of their own as well.
