2 women kidnapped by Indians

Hello, I'm looking for a TV movie that aired on M6 about 5 years ago. I would really like to know the title. The story is about a woman who is supposed to marry a man she doesn't know; she is not happy. One day, she goes with a friend (or a family member) in a horse-drawn carriage, and there's nothing but fields on the horizon. That's when some Indians come and kidnap them. They stay with them for a long time, and one day they want to escape, but the Indians chase them down and catch them. She falls in love with one of the Indians, and in the end, he frees them. Her husband knows that she was happy there, so he lets her reunite with that Indian.
