Jenn finds herself completely alone on a small tropical island after a boating accident. By day, every ounce of her strength, cunning, and courage is strained simply to find food, outlast the elements, and survive. But as the sun sets, Jenn’s waking nightmare inexorably grows into terror, when a malevolent shadow rises from somewhere offshore to stalk the jungle for prey. From Blumhouse, producers of Get Out and The Purge franchise, comes a sinister twist to the castaway genre in this horrifying thriller.
