Martin lives in the city with his mum. He′s come to walk the boundaries of the farm that′s been in his family for generations. It sounds easy, especially as he′ll own the land when he gets back. Martin′s great-grandfather, Ted, doesn′t even want him to walk around the farm′s fences, just up the gorge and along the hills. But up in the gorge Martin meets Meg from almost a century ago and Wullamudulla from thousands of years in the past. Despite their differences they discover that they′re all on the same journey ... and that walking the boundaries means more than following lines on a map.
