Brian Kernohan travels to the Dark Hedges to ask why we make the choices we do in life. He meets Dawn Purvis at a photoshoot and talks to her about her journey from young mum, to politician and on to the public face of the Marie Stopes Clinic. He also explores different paths others have chosen to take with victims campaigner Raymond McCord, Patrick Cregg from the Woodland Trust and people who live and work near the Dark Hedges.
