Back in high school, Tracy, Olivia, and Holly were the girls everyone wanted to know, and their bond survived the years. Now, two decades later, Olivia's wealthy Italian husband has died, and the women reunite on a luxury sailboat crossing in the Caribbean. Together with Tracy's college-aged daughter and an attentive two-man crew, they sail into paradise. Then the smallest mistake triggers a series of devastating events. Suddenly, in a desperate fight for survival, the women battle the elements, the threat of modern-day piracy, and their own frailties...as they discover how facing our mortality tests the truth of everything we think we know.
