This movie is a horror movie. There was a group of family or friends in a bus then they got lost and they didn't have gas and then a person came to the grandma and opened her stomach and then they took a little girl from her dad to a cage where they were going to eat her and then her dad had a Walkie talkie that connects to the person who was who was going to eat their daughter. Please help me find this horror movie I will gladly appreciate it :).
