The Swallow.

Ziggy and her four friends journey out on a camping trip to a picturesque remote forest. But trespassing into an off-limits area, they awaken an uncanny terror in the woods... and a ravenous hunger from within the Earth. Soon, the ground itself is trying to swallow anything and anyone it comes into contact with and Ziggy and her friends have nowhere to run as every trembling step they take could be their last.
