Children's show from early-mids 90s (fantasy, I think)
Do you recall a (non-animated) movie with a young girl, witch, gate with special key, and possibly a unicorn? I don't remember if it was actually a movie - could have been a mini-series or possibly even a TV show. The main character was a young girl. There was a witch, a gate with a special key, and possibly a unicorn. The girl was always trying to find some key for a gate or something like that. I saw it in school, in 2nd grade, roughly about 1994/95. If you can remember, please post! I've been trying to remember for years!
