hello everyone! I remember watching this movie as a child, but I only remember a random scene. I believe it's from the 1980's... the kids are running/hiding from someone or they have been kidnapped(?), and they end up on a treasure hunt in a cave. I believe it has something to do with ghosts, or they think they are ghosts. I know I'm being vague, but it's been driving me crazy forever! Thanks for any help you can give me!
