Charlie's Ghost Story (1995)

"An Adventure Like No Other"

Charlie is a kid whose archeologist father has made several discoveries while exploring a cave in Colorado. However, Charlie makes a discovery of his own -- the spirit of a long-dead explorer has come back to haunt him until his remains can be recovered and finally buried in a proper place. But Charlie can't manage this task on his own, with his old man being too busy with his work to aide the restless soul. What's a supernaturally-afflicted lad like him to do?
