In the first episode of the series, Kate Humble and her Welsh sheepdog, Teg, explore remote corners of north Wales. Kate reaches for the sky, amidst a storm with 50 mph winds, as she attempts to climb the tallest man-made structure in Wales to fix some loose cables on the Arfon Transmission Tower. Next, avid walkers see rivers as a barrier, having to find a bridge or get wet, but Kate learns how to overcome natural obstacles with the novel activity of packrafting – using an inflatable canoe weighing only 1.5kg. On the north east coast, Kate meets a pack of dogs trained to carry out wildlife conservation by sniffing out endangered species, and on the north west coast, Kate digs and prepares a grave for a new resident, who in death wants to give himself to help nature thrive. Kate experiences a moving funeral at the only woodland natural burial ground in the area.
