Story Synopsis:
A woman traveling down a long and lonely road happens across a deserted school bus that leads her down a trail of terror in this backwoods shocker from director Stephen Goetsch. Maria is driving though the country when she happens across an apparently empty school bus with the words "Help Me" hastily scrawled on one of the windows. Just as she steps into the bus to investigate further, a madman steps aboard and starts up the engine. But the school bus wasn't empty, because there was a young girl hiding inside. When Maria and her terrified passenger arrive at an unknown destination deep in the desert, they quickly discover that everything they thought they knew was wrong. But who can Maria and the girl trust, and what will become of them if they make just one false move?
