searching for native american movie – 1975 (?) – character named kiona

i’m looking for the name of a movie made in the 1970’s (i think) which features an actress named linn. in the movie her name is kiona. my girlfriend is named after this actress (linn-kiona) and i would really like to be able to show her this movie. any help is much appreciated.

i appologize if this forum is not meant for these kind of questions, i just cant find any other way and it would really help me a lot if i can find this movie.

many thanks,
