This is a rarely-seen Czech movie from 1948.  It's about a wild village girl who gets into trouble with the other villagers.  She goes barefooted a lot.  She skinny dips in a lake, causing the local boys to get hot and bothered.  She's even rumored to be a witch!  But she does have a couple friends.  One is another girl of the village who is her best girlfriend.  Another is the son of a woman she treats; they eventually become lovers.
Things come to a boil when a trick she plays to help her girlfriend avoid an arranged marriage backfires, and the villagers try to kill her.  But it has a happy ending.
This reminds me, a bit, of Green Mansions with Audrey Hepburn which, of course, was made several years afterwards.
All and all, a wonderful film which I highly recommend!
