Marcus (Xavier Samuel) and Liz (Georgina Haig), and Greg (Bob Morley) and Nina (Sophie Lowe) are on a road trip. On the desolate and silent national highway, they got into a feud with a giant truck and were then knocked off the national highway by each other. Although he narrowly escaped, Greg suffered a severe fracture and was at stake. After some emergency rescue, Marcus temporarily bandaged his friend. At this time, they found that the truck was parked not far away, and the driver did not know where to go. Soon the driver attacked the four people with a gun. In an emergency, they drove the truck away, and in a daze, Marcus drove the car to a dead end. He and Liz went to seek help together, and the two got separated after a quarrel in the middle, and they each encountered a terrifying experience.
At the same time, Greg accidentally opened the door of the truck container, and his temperament seemed to change after coming out. This giant truck seems to have incredible magic power, and it is brutally swallowing these four young people.
