Mara of the Wilderness (1965)

A child of nature! Untamed! Untouched! Survives all nature's fury

An altruistic park ranger stumbles upon a beautiful but feral young girl who spent most of her life being raised by a pack of white wolves. But his plans to tame her wild ways are cut short when an enterprising trapper hears about her story and sets out to sell her as a freak to a traveling side show.
