Jack and Ashley's search for eight-year-old Sammy has left them hopelessly lost in a twisted maze of tunnels deep inside Carlsbad Caverns.

Bats are everywhere, and the echoes of their screeching cries sends a chill through the trio. The only light is the candle in their lantern. What will happen when it burns out, leaving them in total darkness?
