Mystery Mansion (1983)

Slow-paced and with mediocre acting, this family-oriented mystery story focuses on the search for a missing treasure and for answers to the disappearance of a young girl nearly a century earlier. Susan (Randi Brown) and her brother Johnny (David Wagner) are on vacation at their aunt's and uncle's house (Jane Ferguson and Greg Wynne) when they come across an old map that may be a clue in finding a cache of gold. Susan has been having bad dreams about Rachel, a young girl who disappeared in 1889 in a nearby mansion (now run-down and crumbling) when her parents were killed by bank robbers. After Susan and Johnny make friends with Billy (Lindsay Bishop) their neighbor, all three children join together to look for the treasure, and to find out what happened to Rachel. In one interlude, two escaped convicts menace the youngsters for awhile, but some clever action by their friend and neighbor Sam (Dallas McKennon) saves the day. Now all they have to do is find the answers to their two big questions -- where is the gold, and what happened to Rachel?
