When four friends who ruled the school twenty years ago gather for an idyllic sailing vacation – meant to comfort Olivia, who has returned home a widow after twenty years abroad – they expect two weeks of gossip, sunbathing and drinks with little umbrellas.
Instead, two days into their crossing, a single small mistake turns paradise a sun-baked hell.
The same elements that combined to make this trip an adventure in paradise combine in for survival. Surrounded by water, but with almost none to drink, with refrigerators filled with gourmet food rotting before they can used it, and a deluxe communication system ruined in an instant, the women must hide from the punishing sun and use all their strength and intelligence to try to outwit nature, their own demons and human predators.
What happens when friendship must face the ultimate test? Does the better nature prevail or is it everyone for herself?
