The escape

I was at a house and I was being held captive. I wasn't kidnapped, but I wasn't allowed to leave. I had to escape and some people saw me escaping, but they were helping me. There were two houses close to each other. One was in a valley and the other was on a hill. I had to get to the house on the hill and I had to be in the air to do this - weather a zip line, or floating I'm not quite sure.
