Three young women, Sarah, Abby, and Lou, get together for a private camp out on an empty island off the coast of Maine, to renew their bond of sisterhood. They quickly learn, though, that the island is anything but empty, when they encounter three men who have come to the island to hunt. A misunderstanding quickly turns to tragedy, and the three women soon find themselves the targets of the hunt. What started as a simple playdate is now a race for survival.
