The Haunted Cave

There is a famous cave located just outside of Spooksville. Many stories surround the dark place: scary ones as well as exciting ones. Hearing the amazing tales, Adam is tempted to explore the cave with his new friends: Watch, Sally, and Cindy. But thte moment they enter the cave, the entrance closes behind them.
And they are trapped in the dark.
They walk deeper into the cave, frantically searching for a way out. The batteries in their flashlights begin to run low. Then they realize something is following them. Something that has been in the cave for a very long time.
Something big and black and hungry.
