One of their crew is the handsome Manuel, who is cursed by his angry ex-girlfriend Maria as he prepares to leave on the yacht.
They bury his body and under Manuel's guidance, set out to build a hut for shelter and find food.
Two days later while fishing near a reef, Manuel finds Jack alive and brings him back to Jennifer and their hut.
Although Jack is grateful at first, he eventually suspects Manuel of having desires on his wife and declares the man his enemy, promising to ruin his life once they get off the island.
As the two exit the water after fighting, Manuel pins Jennifer down and starts to rape her as a way of getting revenge on Jack, but she soon stops resisting and the act becomes consensual.
They are forced to swim back to the island and to Jack, who attacks the exhausted Manuel with a spear and kidnaps Jennifer.
One year later, a yachting family drops anchor near the island and explores it, discovering Jennifer asleep in her hut.
Jack, who is fishing, sees her leaving on the yacht and calls out, but Jennifer, who had also stolen his lighter so he could not make any more fires, finally exacts revenge on him by ignoring him and the family inside the boat cannot hear him.
The Daily Press called the film "Not the best retelling of the rich-poor love triangle..."[9] Three, as it was known in the UK, suffered from poor reviews, gaining a rare one-star rating on the BBC Movies website.
[10] Robert Hanks of The Independent said "[Three is] an unholy amalgam of Lord of the Flies, The Blue Lagoon and The Admirable Crichton ... At odd moments it rises to risibility, but mostly it is just dull".
[12] Anna Smith of Time Out criticised the film's tone in her review saying, "the dramatic score and writhing sex scenes imply an erotic thriller, but the camera treats pneumatic Brook like the subject of a cheap porno and the plot bears little resemblance to either genre.
