Suffering from trauma after a dramatic event from the past, Meg (Hiftu Quasem) wonders for a long time whether to take part in the exclusive wedding of her friend Lizzie (Lauren Lyle), organized in paradise outdoors. Eventually, however, he arrives in the Caribbean with Cam (Nicole Rieko Setsuko), Ruth (Ellouise Shakespeare-Hart) and long-lost friend Kayla (Natalie Mitson) as his companions. When the women decide to go on a solo boat trip, they have no idea that the idyllic trip will turn into a fierce fight for survival. Soon, left on their own and drifting in the open sea, they will be forced to struggle not only with extreme exhaustion, but also with attacks from killer sharks. Do they have any chance against predators that nature has turned into real killing machines?
