When I was about 8yrs old I remember watching a movie that was set in the late 70's about a girl who was about 15 or 16yrs old and she began seeing an older man. The man did know her real age because she said she was about 18yrs old. During the whole movie she tried to hide the age thing. I thought that a young kristy mcnichol was in this movie, but when I do a search I can't find it. Anyone else know. Please help, I've been looking for it for very long time.
Thanks:)

I searched IMBD for it, and that's all I can come up with that MIGHT be close.

Sorry if that's not much help :(

Thanks for your help. That is exactly what I found too.
