Eric (Luke Mitchell), Jennifer (Jessica McNamee), Yolanda (Amali Golden), and Mitchell (Benjamin Hoetjes) are four adventurous friends who travel to northern Australia to explore an uncharted cave system. Despite receiving news that a huge storm is on its way, they decide to press on, thinking that they will be safer inside the cave. Unfortunately for them, a flash flood occurs and pushes them further inside the system than they would like, sealing them in in the process. Lost and disoriented, they gear up to face a far more dangerous threat: crocodiles. Directed by Andrew Traucki.
