I see my son in the Northern Lights

Chasing the aurora helps Hugo grieve. By day Hugo Sanchez works in a school, but by night he hunts glowing light displays across the freezing Canadian wilderness. Capturing the aurora is more than just a hobby for Hugo. He took up photography after his son Emilio was born with complex disabilities. When Emilio died at ten years old Hugo found solace and hope in the dancing night sky. Presenter: Emily Webb Producer: Louise Morris
