Many years ago, the young bandit El Diablo disappeared into a cave, never to be seen again. Now an eerie moaning sound is coming from his old hideout, and the ranchers who live nearby think he may still be alive.
The Three Investigators set out to explore the moaning cave--and soon wish they had come armed with more than a flashlight!
